Så här fixar du WordPress White Screen of Death (steg för steg)

Den vita skärmen av död kan vara en webbplatsägares värsta mardröm. Detta frustrerande WordPress-fel gör att du stirrar på en tom sida utan att få några ledtrådar om vad som gick fel.

Till rågaallt kan detta vanliga WordPress-fel ibland påverka specifika delar av din webbplats, t.ex. adminområdet eller enskilda inlägg.

Vi har till exempel sett den vita dödsskärmen inne i WordPress adminområde medan allt annat fungerade bra. I andra fall såg vi det bara när vi tittade på ett specifikt inlägg.

Att förstå de grundläggande orsakerna till detta fel är det första steget mot att hitta en lösning. Den här guiden kommer att ta upp några lösningar för att åtgärda den vita skärmen av död och ge handlingsbara steg för att återställa webbplatsens funktionalitet.

How to Fix the WordPress White Screen of Death (Step by Step)

Note: Innan du gör några ändringar på din site ska du se till att du har en backup av din WordPress-webbplats. Om du inte har tillgång till admin area, se vår guide om hur du manuellt skapar en backup av WordPress database.

Varför ser du den vita vyn av döden i WordPress?

När du ser en vit vy när du försöker besöka din website i WordPress betyder det för det mesta att ett skript på din website har förbrukat minnesgränsen.

Skriptet som inte svarar dödas antingen av din WordPress server på webbhotellet eller så tar det helt enkelt slut. Därför genereras inget egentligt message error, utan du ser bara en tom vit vy.

Ibland kan du dock se ett error message.

Du kan till exempel se ett critical error message i stället för en tom page.

Critical error in WordPress

Om du ser en tom vy eller meddelandet ”There has been a critical error on your website”, så är det samma fel.

Detta error kan också uppstå på grund av ett dåligt kodat theme eller plugin installerat på din site. Ibland kan det hända om det finns en issue med din web server.

Eftersom error på vit vy kan orsakas av många olika saker, är det obligatoriskt med metodisk felsökning för att fixa det. Här är de steg du bör försöka:

Om du föredrar skriftliga instruktioner är det bara att fortsätta läsa.

1. Kontrollera om problemet uppstår på dina andra webbplatser

Om du har andra WordPress-webbplatser installerade på samma webbhotell konto, då vill du börja med att kontrollera om problemet händer på andra webbplatser också.

Om det är så, är det en stark indikator på att något är fel med ditt webbhotell för WordPress. Detta kan vara en tillfällig issue som påverkar deras tjänst, och du måste kontakta deras support för mer hjälp.

Å andra sidan, om the issue bara inträffar med en website eller en viss del av den webbplatsen, då vet you att problemet är med just den webbplatsen.

2. Fixa error med vit vy med WordPress återställningsläge

Om erroret ”White Screen of Death” orsakas av ett plugin eller theme för WordPress, kan WordPress kanske fånga upp det.

Den nya funktionen för skydd mot fatal errors som introducerades i WordPress 5.2 kan ibland fånga upp error, så att du kanske inte ens ser en vit vy. Istället kommer du att se ett message om att webbplatsen har tekniska problem.

This Site Is Experiencing Technical Difficulties Error Message

WordPress kommer också att skicka ett email om problemet till din admin email address.

Emailet kommer att ha rubriken ”Your Site is Experiencing a Technical Issue”.

Technical Difficulties Email With Link to Recovery Mode

Detta email message kommer att peka ut det plugin eller theme som orsakar error, och det kommer också att innehålla en speciell länk.

Denna link allow you to logging in to the WordPress recovery mode and deactivate the faulty plugin.

WordPress recovery mode dashboard

Men om du ser den vanliga vita dödsskärmen utan alternativ för email eller återställningsläge, måste du fixa felet manuellt.

3. Öka limit för minne

Vanligtvis beror detta error på att ett skript har förbrukat din web servers minne och avslutats mitt i.

För att fixa detta måste du öka PHP-minnet som är tillgängligt för WordPress. Detta kommer att allow skriptet att använda mer minne för att slutför det jobb som det var tänkt att göra.

Du måste editera wp-config.php-filen på din WordPress site eller använda ett code snippet plugin som WPCode.

Du kan följa instruktionerna i vår tutorial om hur du ökar PHP-minnet i WordPress.

4. Fixa felet med vit skärm genom att inaktivera alla tillägg

Om det inte hjälpte att öka minnesgränsen för PHP, eller om du har en hög minnesgräns, gillar 256M eller 512M, måste du börja med troubleshoot.

I vår erfarenhet av felsökning av detta problem har vi alltid funnit att issue är antingen med ett specifikt plugin eller ett theme. Låt oss gå vidare och inaktivera alla tillägg.

Om du fortfarande kan komma åt WordPress admin dashboard, kan du helt enkelt gå till Plugins ” Installed Plug ins page. Välj alla installerade tillägg och välj sedan ”Deactivate” i dropdown-menyn ”Bulk actions”.

Deactivate all WordPress plugins

Men om du inte har tillgång till admin area i WordPress måste du deactivate alla tillägg via FTP.

Anslut först till din WordPress site med hjälp av en FTP-klient eller din hosting providers filhanterare. När du är ansluten går du till mappen wp-content, där du ser mappen tillägg.

Nu måste du högerklicka på mappen plugins och sedan välja ”Rename”. You can rename the plugins folder to ’plugins-deactivated’.

Using FTP to Rename the Plugins Folder

WordPress letar efter en folder med namnet plugins för att hämta alla tillägg. Om den inte hittar denna folder deaktiveras helt enkelt alla tillägg.

Om detta fixar problemet aktiverar du ett plugin i taget för att komma till botten med problemet. När du har hittat det plugin som orsakar problemet kan du ersätta det med ett alternativ eller rapportera problemet till plugin-författarna.

5. Activate standardtema

Om felsökningen av plugin inte fixar problemet, bör du försöka ersätta ditt aktiva tema med ett standardtema.

Anslut först till din website med en FTP-klient och gå till mappen /wp-content/themes/. Den innehåller alla teman som installerats på din website.

Högerklicka för att selecta ditt nuvarande WordPress theme och downloada det till din dator som backup.

Using FTP to Download the Current Theme as a Backup

Därefter måste du ta bort ditt nuvarande theme från din website.

Högerklicka bara på din theme folder och välj ”Delete”. Din FTP-klient kommer nu att delete temat från din website.

Using FTP to Delete the Current Theme

Nu, om du har ett standardtema för WordPress som gillar (Twenty Twenty-Two eller Twenty Twenty-Three) installerat på din website, kommer WordPress automatiskt att börja använda det som standardtema.

Men om du inte har ett standardtema installerat måste du installera det manuellt med FTP.

Om detta fixar problemet, bör du titta på ditt temas functions.php-fil. Om det finns extra mellanslag längst ner i filen måste du remove dessa, och ibland fixar det the issue.

Om du använder en dåligt kodad funktion i ditt temas functions.php-fil kan det också orsaka error med white screen of death.

Överväg att downloada en ny kopia av your theme från källan och sedan installera det manuellt med FTP.

6. Aktivera debug-läget för att fånga upp error i WordPress

Om inget har hjälpt hittills är nästa steg att slå på debug i WordPress. Då sparas error logs som allow you att se vilken typ av error som skrivs ut.

Add helt enkelt följande kod till din wp-config.php-fil:

define( 'WP_DEBUG', true);
define( 'WP_DEBUG_LOG', true );

När du har addat detta kommer den tomma vyn nu att innehålla error, varningar och notices. Dessa kan kanske hjälpa dig att hitta grundorsaken.

Om du inte ser några fel kanske du ändå vill kontrollera debug-loggen.

Besök bara wp-content foldern på din website med hjälp av en FTP-klient. Där hittar du en new debug.log-fil som innehåller en logg över alla fel, notices och varningar.

Debug log

7. Clear cachen i WordPress

Ibland kan du ha tillgång till back-end, men front-end av webbplatsen har den vita dödens vita vy.

Detta kan hända på grund av ett plugin för caching. I så fall behöver du helt enkelt tömma din WordPress-cache.

Du kan se vår guide om hur du clearar cachen i WordPress för detaljerade instruktioner.

8. Fix the White Screen Error för längre artiklar

Om du bara har en vit skärm av död på en mycket lång post eller page, kan den här metoden fungera.

Detta trick ökar i princip PHP:s textbehandlings-capability genom att öka recursion och backtrack limit. Du kan klistra in följande kod i din wp-config.php-fil:

/** Trick for long posts */
ini_set('pcre.recursion_limit',20000000);
ini_set('pcre.backtrack_limit',10000000);

Vi förstår att detta är ett mycket frustrerande error, och vi hoppas att ett av knepen ovan har löst problemet för dig.

    I need to downgrade 3.9.2 to 3.9.1.

  3. Sylvester Lapisang

    Thanks for the post, deactivated all the plugins and it worked, Zopim Chat was the problem

  4. wohfab

    It was a crashed functions.php for me (desptie I did not change anything o.o) – THANK YOU SO MUCH!

  5. Aleksandar

    Great tips. In my case (WP v.3.5.1) problem was plugin wp-super-cache. I just delete it and all works ok. I didn’t have time to update and upgrade instalation and plugins.. So maybe this helps.

  6. Chris

    Thanks, both removing plugins and changing themes to default worked for me. but my prob is i can’t activate my plugins. it’ll just open another white screen of death. all plugins.

  7. Hans Haupt

    Thank you so much for your post.

    I tried updating my theme and was met with the ’White Screen of Death’.

    I took your advice to delete the problematic theme from the site cPanel and ’presto’, I was able to log back into wordpress and change the theme to one that works.

  8. Bryan Myers

    Here’s something else to look for- make sure you close out the php tag on the page information block (not sure of it’s real name) at the top of your template page. doh.

  9. Kaveh

    Thank you so much
    Your instruction helped me fix my problem :)
    tnx again

  11. Tommy

    Hey all I had this problem too and found a solution. It seemed to happen from updating from 3.71 to 3.72.

    Ok so I tried the following:

    rename plugin folder
    delete theme
    change memory in config file
    report errors in config file

    I then saw the error:

    Parse error: syntax error, unexpected $end in /home/public_html/wp-includes/cron.php on line 247

    I checked the cron.php and it looked like loads of the code was cut off because it endee with a comment. So I uploaded a new cron.php file from wordpress and it worked.

    I hope this may help others who have this issue.

    Thanks

  12. Mike

    It’s the first time I write here. In my case, everything is blank, I can’t even log in with
    It is still under construction, so I just uploaded a new theme and all went blank.

    I know I have to revert the theme to the ”twenty twelve”, but how? If I can’t even log in.

    any help?! THANK YOU

    • WPBeginner Support

      Connect to your website using an FTP client, go to /wp-content/themes/ directory and delete the theme you just uploaded. If your webhost offers cPanel, then you can use file manager in cPanel to delete the theme.

    Here’s another way to get WSOD! My template, from Yoo Themes, generates a ’cache’ directory. I accidentally filled the drive with this website causing a zero byte cache file.

    root@www:/var/www/wp-content/themes/yoo_vanilla_wp# ls -l cache/
    total 32
    -rw-r–r– 1 www-data root 25 Mar 13 16:41 index.php
    -rw-r–r– 1 www-data www-data 0 Mar 13 16:43 xml-9ae22c153220f9eda980e5ec3b598954.php

    Delete the ”xml*.php” files in here after you’ve cleaned up your drive … back in business.

    That only took a couple hours of hunting – groan.

    • Ope

      Sorry i deleted the xml.php file but it still came back the moment i refreshed the wp-admin page. yet WSOD persist. Any help. am using a yoo theme too

  14. Michelle

    I have this White Screen on my website, have tried EVERYTHING and nothing working. I cannot access my wordpress login or admin page. It is a new website, so I dont mind wiping it clean and starting again, but I have tried to upload a fresh install of wordpress 3 times and it keeps crashing dreamweaver. Is there any other way I can fix this?? Need help Please :(

  15. Aamna

    I am a subscriber of your site and my client is also seeing the white screen of death
    I have used all the fixes but still no success
    What I fell is that I think my clients site’s wp-content has unnecessary folders like
    1- backups (files in this folder are ( .htaccess, .backup_running, database_arcproject_co_u.sql)
    2-cache
    3-uploads(it has many folders of images)
    Please tell me what should I do?
    Thanx

    • WPBeginner Support

      First make sure that your client has a backup. If they don’t have a backup then you need to create one now before you make any further changes.

      After that you can start deleting the unnecessary files from wp-contents folder. Try deactivating all plugins by renaming the wp-content/plugins folder to wp-content/plugins.old.

      Administratör

      • Aamna

        I have tried disabling the plugins but it didn’t worked.
        Anyways how can i take a backup of the site?

        • WPBeginner Support

          In case you don’t have access to the admin area, you would first need to make a database backup manually. After that you would need to download all the files from the website, using an FTP client.

  16. AJ

    One of the most common causes of whitescreen is white space at the beginning or end of a functions.php file or other php file. Often when cutting and pasting or simply editing code a line break gets in at the top or bottom and bam!!…

    Look before the tag at the bottom.

  17. jd

    i did some testing and have uploaded a new theme to the server and have added no limit on the memory and reinstalled the wp to current one. and what i found out to be an issue is with the SQL data base.. when wp tells the SQL server that i have deleted or updated info it seems to keep everything even the deleted items.. NOw the big question what did i do to fix it. well i went to the data base and erased the whole thing and then renamed it back to the same one and went to my site and enter some basic info that showed up .. and BAMMM no white screen i went and turned on the theme and continued my adjustment and creation

  18. Lea

    Hi,

    I took over a WP website for a client and I logged in once, updated the pluggins and since then, I can’t enter the Admin section of WP nor see the website. White screen of death indeed, for both.

    I have read in the comments part above that someone had the same issue, which you directed to the article ”Locked out of WordPress admin area.” Unfortunately, in that article, you direct the person with a White screen of Death to the ”How To fix the WorldPress White screen of death” article, which is this topic here.
    So… I am a beginner to WP and I am lost. + my client hasn’t had a website for the past 24 hours.
    I would really appreciate some help or re-direction to a tutorial/article that tell me how to actually access my admin page !

    Thanks a lot in advance.

    Lea

      Renaming wp super cache plugin directory in ”Plugins” folder resoved the issue

  21. Boby

    Hey, my WordPress page only can visit by me (admin), when i logout, the homepage is white screen. please help

    • WPBeginner Support

      Try switching to a default theme like twenty thirteen or twenty fourteen. If this does not solve your problem, then disable all installed plugins. Also update your permalinks.

    Tried to update my blog today and had problems (was using WordPress app for android). Had considered it to be an app problem and reinstalled it before considering to actually check the site (something I should really have done in hindsight). As I have more than one blog hosted on the same site (the other being fine) I started to get panicky. After diving into a net-cafe I managed to find this trouble shooting guide and now I’m back online.

    Thank you.

  23. Lark

    I’m working with the Roots theme. Turned on the computer and had a white page. Had no memory of what I had done a few weeks before. Replacing the custom theme with the default theme and then undoing changes to scripts.php and widgets.php worked for me. Wow, simple solution, but sometimes it’s quite hard to see simple troubleshooting through the panic… Thanks so much!

  24. Claudia

    Great help. 1000 Thanks
    My issue resolved.

  25. Ian

    Thank you. I thought I’d lost everything.

  26. Cesar Pietri

    Thanks,
    It was a great help
    In my case solve rename the plugins folder.

  27. Lois Wakeman

    Another cause that I just found (WSOD in site and backend) after upgrade.

    Manual upgrade via FTP was interrupted by a lost connection and somehow a file got missed.

    I used your helpful instructions to turn on debugging having ruled out themes and plugins as problems, which allowed me to trace the offending file and upload it. Voila!

  28. soeb

    Thanx it was a great help..!
    In my case it was functions.php file.

  29. Rhodon

    I had to activate the debug mode, and this is my error:
    Warning: require_once(ABSPATHwp-admin/includes/dashboard.php): failed to open stream: No such file or directory in /var/www/domains/rhodon.nl/www/wp-admin/index.php on line 13 Fatal error: require_once(): Failed opening required ’ABSPATHwp-admin/includes/dashboard.php’ (include_path=’.:/usr/share/php:/usr/share/pear’) in /var/www/domains/rhodon.nl/www/wp-admin/index.php on line 13
    How can I solve this?

  30. Junior

    I had to use the edit phpMyAdmin fix to finally get it to work. Editing the database is never fun but your clear instructions made it easy. THANKS!!!

  31. Thomas

    It was the blank lines in functions.php

    Thanks so much!
    Finally read it in the comments.

    • JohnLionFlow

      Same here! Removed the blank lines in my theme’s functions.php file and it worked.

    • earthora

      I had the white screen on everything, front and backend, was starting to panic. I removed the last blank line in functions.php and I’m all back up and running. How would it get there? I’ve never opened it on this installation?

  32. Christal

    I was able to get out of the ”white screen of death” by changing my file name from plugins to plugins-temp, but then my site had reverted back to the old theme, and when I reverted to my new theme (which was installed about a month ago), all of my plugins and widgets were gone! It’s a very basic theme with all of the customizations gone! How do I recover all of this??

  33. Niné

    THANKS A MILLION!!!!

  34. Eric Gitonga

    I had to go into phpMyAdmin and into my MySQL database to drop all the wp-* tables created from a previous WordPress install before I could solve the White Screen of Death problem. It now works just fine.

  35. Ilke

    Hi,
    I was very happy with your advice once about a year ago with a white screen on the entire front-page of a wp-website. Unfortunately, this time (and for another site) it doesn’t work so far.

    I extended the memory several times (I’m at 512M now) and changed the auto keys, that didn’t help. Now I renamed the plugins-folder to plugins.deactivated, and I get this error message:

    Fatal error: Cannot redeclare _1059195956() (previously declared in /public/sites/www.name.nl/wp-includes/version.php:9) in /public/sites/www.name.nl/wp-includes/version.php on line 9.

    Any idea what else I can try?
    Thanks for sharing all this useful information,
    Ilke

    • WPBeginner Support

      Try renaming your theme’s folder as well. After that you need to download WordPress and upload a fresh copy of themes folder to your site. WordPress will now fall back to default twenty thirteen theme. Let us know if it worked for you.

      Administratör

      • Ilke

        I did rename the current themes folder and uploaded a fresh themes folder from a new wp 3.7 download. Unfortunately, that gives me a white screen altogether on the front as well as the back office and I still receive the same error-message.

        With debug set to true in wp-config I got
        Notice: WP_User->id was called with an argument that is deprecated since version 2.1
        and a few other deprecated notices as well as a notice that wp_enqueue_script and wp_enqueue_style was called incorrectly, which both refer to the functions.php

        This is really starting to worry me. Do you happen to have some other advice still?

        Best,
        Ilke

      • Ilke

        I also tried renaming the plugins-folder and uploading a fresh one. And I cleared the cache. Still I get the same error-message. Since (with debug set to true on wp-config) I get Notice: undifined index-messages concerning two plugins, should I delete those?

  36. Puja singh

    Hi, I am facing the same blank page problem for my site . I tried most of the mention step
    Disable all plugin
    Activate the default theme.
    increase the memory limit to 128 MB.

    but no luck, any help will we appreciated.

  37. suneel

    Life saving tutorial…

    Thank u very much

  38. Justin

    Thank you. I seem to get it when I’ve been making lots of updates to my site, then I get locked out and have to wait. A memory issue would make sense. Time to clean out a bunch of unused plugins.

  39. Michael Lambertz

    Another reason can be false permissions… I tried to copy a wordpress directore via unix command cp -R, and after that all copied files weren’t in the group www-data. chgrp www-data wordpress_dir/ -R did it for me ;-)

  40. Jacob Worsøe

    I have periodically white screens on both frontend and backend. The white screens occur in a completely random pattern. Are the recommendations the same in my situation or do they only apply to more permanent issues?

    • Editorial Staff

      Yes. It seems like you’re site is running out of memory because of a process that’s being ran. So the process is the same.

      Administratör

  41. Hossein

    thank you soooooooooo much, my problem solved, it was because of blank lines in my functions.php

  42. LC

    I can’t even enter the Admin section of WP. I get the blank page. What should I do?

  43. Rosie

    Thanks, this was useful. I had the white screen on the live site, but WP admin was fine. I use WP Super Cache and I cleared the cache with no effect, then deactivated all plugins, and when I’d tried everything else I suddenly thought of the expired cached pages.

    If you use WP Super Cache you have to delete the expired cache too. That worked right away. Then I set my garbage collection (on the Advanced tab) to hourly instead of daily, to try to prevent it happening again.

    • Tom B.

      Hello .. thought I might add 2cents,

      I’m using WP Super Cache too and often crashed to White Screen. Looked at the wp-config.php file and found they were putting their instructions above the SQL allocation in the script, so I moved them down and added the ’default Memory Limit’ tweak and now my site http://webinardatabase.com/ smokes!

      REF:
      First save a unmodified copy of wp-config.php to your HD.

      Open your wp-config.php, which is located in the root WordPress directory.

      Locate the WP Super Cache code (their code is obvious –three lines- the fourth is a duplicate, but I left it), and move them down (I put mine above the SALTS).

      Then add the following line: define(’WP_MEMORY_LIMIT’, ’64M’);
      Just BEFORE the super cache, seemed logical.

      And save, check performance.

      IDK, I think this is a bug. Made no sense to be allocating cache before opening the SQL database.

      Worked for me. Prost! — Thanks Wpbeginner.com

      PS: Just noticed the post below, WP Super Cache requires permalinks be set to post name, this error appeared on a fresh install. 2 more cents.

      • Tom B.

        Follow-up.

        Had to kick WP Super Cache to the curb.. too buggy.. Gone with W3 Total Cache.

        Lone Watie: We thought about it for a long time, ”Endeavor to persevere.” And when we had thought about it long enough, we declared war on the Union.

        Union = WP, really is this the answer?!

        • Tom B.

          Ps: Once the plugin is deleted, return to wp-config and manually remove WPSC lines.

          Really, no, really!?!

      • Glenn "TheeMahn" Cady

        Tom, I would like to personally extend a much deserved thanks.

        My wpconfig had define(‘WP_MEMORY_LIMIT’, ’64M’); after supercache, moving it above has closed my ”White screen of death issue.” I had been refreshing for months. The site now seems fairly snappy.

        Thanks again Tom,

        TheeMahn

  44. Jacobus

    Personally I haven’t had this problem, yet, I have the problem that I have to reset my permalinks all the time because of endless redirects. Drives me crazy. Every time I publish a new post on my blog I have to set the permalinks back to standard and then back to post name. Do you know if this is host related or plugin related?

  45. Manish Anand

    Yep, turning on Debug option helped. It was incomplete uploading of query.php file.

    Thanks

  46. Joel Andrew Glovier

    Here’s another suggestion when none of the above works, try flushing your rewrite rules cache.

    I had a single page on my site returning as a blank page, and tried almost every solution above, as well as some other things (like installing Debug Bar plugin, etc) to no avail.

    I was able to narrow it down to what I assumed to be a premalink issue, however, since the page had been working before, and stopped working; and also because even when I used a different page template it still was not working properly (I had prior to that assumed to had to do with my custom wp_query in that page template).

    So I started investigating the WordPress rewrite system, and came to find out WordPress keeps a cache of all the custom page slugs and rewrite rules. (more about that here: http://codex.wordpress.org/Rewrite_API/flush_rules and here: http://codex.wordpress.org/Function_Reference/WP_Rewrite)

    I also found that this method is used to flush the rewrite cache: $wp_rewrite->flush_rules();

    So I tried just adding it to the second line in my functions.php file, and after one page refresh the page contents showed up again.

    IMPORTANT: make sure to remove the method after using it once, as there are some costly performance hits associated with leaving that code in your file. You should only need to use it once to resolve the issue, however.

      Saving the permalinks settings again will also flush the rewrite rules from our understanding. Thanks for the suggestion about this :)

        Yeah, but that didn’t work in my case. In fact, normally you don’t even have to save the Permalink settings page, just visit it. But in my case that neither visiting, nor saving, nor chaning to another setting and changing back worked.

        But actually I discovered it was something much more obscure, and the flushing was only a temporary band-aid.

        Turns out I had a conflict between a page with the title/slug of ”team” and a custom post-type with the rewrite slug of ”team”. The custom post type ended up winning out, except when I put the rules flush in place, in which case it stopped it from winning out.

        But the real reason I was getting the white screen was because when the custom-post type slug was winning out, it was defaulting to rendering the page with the archive.php file, which I had created (as my theme is from scratch), but not put any markup in yet. The file was completely blank, hence my white screen.

        Womp womp womp wanhhhhh.

          Yup that would do it. We learnt that the hard way by looking at one of our user’s themes.

      !!IF YOU TRIED EVERYTHING THIS WILL WORKS!!!

      Nothing else could even make a change in the BLANK PAGE.
      I put that code an recivied a error, after that I removed it and the website was online again!

    Whenever you’re testing themes or plugins, always leave a tab for ”Themes”. In case of WSOD, you may still able to activate the default twenty eleven themes.

      That doesn’t work if your admin is also locked. The next screen will just return a white screen of death too.

        It could? May be I haven’t reach the Admin Lock level so, I guess we should leave the tab for the phpmyadmin page instead +_+

    Damn! Just seen the section in the article about the functions.php file – oops! Oh well it will teach me not to read so quickly!

    Another ’gotcha’ is whitespace below the closing ?> in your functions.php file. I got this once a while back and deleting the whitespace below it solved the problem. This can also cause a white screen after hitting the publish button as well.
