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 råga på allt 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.
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.
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:
- Check Whether the Problem Happens on Your Other Sites
- Fix the White Screen Error With WordPress Recovery Mode
- Increase the Memory Limit
- Fix the White Screen Error by Disabling All Plugins
- Activate the Default Theme
- Enable Debug Mode to Catch Errors in WordPress
- Clear the WordPress Cache
- Fix the White Screen Error for Longer Articles
Video Tutorial
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.
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”.
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.
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”.
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’.
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.
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.
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.
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.

can someone please help me, when i install a wp themes i keep getting white blank screen, but i still have access to my wp admin, just the website is giving me difficulties, i also see an error log in the root folder
error, responseINVALID
who can help me ?
Melissa
How are you supposed to alter anything when you’re locked out? The white screen of death has happened to me and it not only happened with the site itself but also on the admin dashboard. It happened because I followed one of YOUR tutorials on how to embed a music playlist to the sidebar. I had no way of recovering the site whatsoever, until someone my editor knows sent me the cpanel login page, except I didn’t have any cpanel login details (and I still don’t – but I’ve been asking for them). I’m now afraid to add anything new to my website in case this happens again. WordPress is not user friendly to those who don’t know CSS and HTML like the back of their hand.
Why is it even necessary for WordPress to lock you out of the dashboard when there’s an issue with your website? The issue I had would have been easy to solve from the dashboard. All that needed doing was for the poor piece of coding to be removed. Is there any other way to access the dashboard in a kind of safe mode other than cpanel?
WPBeginner Support
Hi Melissa,
We understand your frustration. White screen of death is a terrible situation for most beginners.
In your case, we feel that you could have solved it but you didn’t have the login details for cPanel. Please make sure that you have those details in the future so that you can easily perform administrative tasks on your WordPress site.

Small contribution : When updating both my WP & Theme I got a WSOD
I struggled to find the solution, reverted to old WP version and tried all the above when I checked the PHP version, I had an outdated PHP 5.2 when the newer theme version only supported PHP 5.3 min.
Keep an eye on your hosting so it stays regularly updated.
Cheers,
JP
Denis
I have experienced the WSOD on a WP site. I found out several WP files on the server were inexplicably empty. I mean the files were there, but had no content anymore. It seems that the empty files were mainly at WP root and in wp-includes. So I just published them again from WP source files, and the blog went live again. No idea why these files had suddenly lost their contents…
Franklin
I mistakenly change the URL of my website, and I can’t access to the dashboard again please help
Clausen
I sincerely hope you found out by now, but you need to access your WordPress DataBase, find your ”wp_option” table and set your ”siteurl” to whatever it was when it was working.
Agnes
Thank you sooo much for this article. I had the dreadful white screen and your tips saved me .
Carrie
I had the white screen come up as soon as I tried to update WordPress to the newest version. Now I can’t access my dashboard at all, just get the white screen. Any suggestions?
Melissa
White screen occurred with trying to add WP Recaptcha Integration to the website. I think it might be something to do with the site having a customised theme. It’s pretty frustrating that WordPress doesn’t have a simple ”safe mode” option you can log into to access the dashboard under these circumstances. I know the CPanel exists, but if you’re a company and don’t have access to CPanel login details and wouldn’t know where to even begin with it, having a WP safe mode login would be most helpful; that way we could go and try to fix the problems without a great deal of hassle. We aren’t all experts; WordPress seems to think everyone using it ought to be an expert at computing and coding. If I could access the admin panel, I’d know to remove the offending plugin and that would probably sort it, but alas! I have to sit here twiddling my thumbs because I’m merely a staff member who was asked to update the website and even the owner doesn’t know the first thing about how to fix these things. WordPress really needs to become more user friendly.
brittney
Have you found a solution?
I am sitting here in the same boat. I cannot access my account to fix the problem! Any piece of information you can give me to help solve this would be great. I totally agree with what you said, WordPress should also have support you can contact!
Carrie
I am back on track. I got fed up with the lack of support from my host so chatted with some new hosting companies that were recommended. The one was amazing, fixed my site (not sure how!) then didn’t want payment just hoped I would consider them if switching hosts. I have now switched and they have been great so far.
Sorry that is not much help to fix the problem unless you are ready to switch hosts. I hope you get your resolved soon.
Mike
Thank you, thank you, thank you, thank you! I activated a new plugin then everything went white. I thought I lost my entire site, the panic was real! I ended up having to deactivate each plugin within the plugin folder and work backwards from there.
Thanks Again,

I have tried every single tip in this guide, with no success. After hours lost, it turned out that I had an empty line in my wp-config.php at the very start, just before the <!php tag. After I removed it, the website worked perfectly again.
Alexander Schilling
The debugging modus brought me on a track: ”Fatal error: Allowed memory size of 33554432 bytes exhausted” since all fixes with the theme, the plugins, with the php.ini and increasing the memory in the wp-config had not worked, I asked my hoster, to increase the memory limit. In this action my hoster finally discovered that I worked with an old php version (5.3) with wordpress 4.6.1 . A change to 5.5 solved the problem and also 7.0 runs wonderfully.
Henrik
My problem is that I can not log in on my computer even if I use different browsers, the screen goes white. But others do not have this problem on their computer.
So what should I do with that?

I found out that if I change to another wifi network, I can suddenly log in! But what do I do to change that so I can log in from my wifi network?

with no access to the PHP files only the WP dashboard, would you go straight to replacing the theme?? It is just the blog section of the site that is blank. If I live preview the site in another theme the blog shows fine.

We had this issue but it stated ”error” in the top left corner of the white screen.
We had recently implemented a new security plugin and I had entered the incorrect password multiple times and so the security plugin blacklisted my IP.
After 15 minutes I can now get back in again.
Luckily I waited before I started on all the above fixes!!
Aleksandar
Another solution – check and remove empty index.htm and/or index.html and/or default.htm
If server config changed (after Apache upgrade), order of index files can change so index.php stay behind plain files.
Had this case once in last two years.
prokops
In my case, wp-admin/post.php blank screen was fixed by removing the ” ?> ” at the end of my function.php in my child theme. I don’t know how the end tag ended in there, but removing it solved my problems.

Thanks for this insightful article. Saved my skin!

I found a hint for this on another site. It is an error caused by a newr version of php more than likely. If your Cpanel allows you change your php version roll it back to until your site works and then you can update everything and go back to the newer versions of php.

I’m helping with a website for a non-profit, I’m not a Word Press expert so i was distressed when I kept getting the white screen with one word ’error’ displayed and could not access any pages on the site through the admin.
My web host couldn’t see anything amiss so he suggested I unplug my router and let it reset. Sure enough it worked. I continue to see the white ’error’ screen but unplugging the router has fixed it every time.
What on earth could cause this? Am working under limitations as it is, this makes it even harder to want to help them out.

White screen, login to WP not working, 3 pages of fake users then found in WP, mess in files on FTP = HACKED WP.
TIP: Do REGULAR UPDATES both: Files from FTP and MySQL database from phpMyAdmin or hosting Administration! Save localy together for these situations.
(TIP: Most of hosters do regular backups about 14 days back)
HOW SOLVED:
1. downloading MySQL database (.sql file) from the hosting administration as a backup.
2. downloading OLD HACKED WP from FTP (hosting) as a backup.
2. downloading fresh installation of WP from wordpress.org
3. deleting WHOLE OLD WP installation from FTP (all files).
4. moving NEW fresh WP to FTP.
5. copy some my folders from OLD WP to NEW WP from folder wp-content: plugins, theme, uploads.
6. installation of new WP and telling it: I have got an existing database, so filling db name, password…
7. after installation WP working ok, login – deleting fake users, unused plugins, themes, check. TIP: WP Settings > General > Turn off option: Anyone can register as a new user.
8. installing plugin Wpdbup for automatic backups, setting its jobs, tests of them.
9. CHANGING FTP PASSWORD, CHANGING USER(S) LOGIN PASSWORD.
10. DOWNLOAD working WP both, ALL FILES from FTP and MySQL DATABASE from hosting or PhpMyAdmin AS A BACKUP.
11. Repeat point 10. always BEFORE a lot of changes of your web and always AFTER them
Jesus saves
Good luck

Today my blog went white like you were describing, but I can’t even get log in or access anything on my site to try anything you’ve suggested because absolutely everything is white. Any ideas on what to do in this case? I’m pretty sure it’s because I somehow messed up the coding in the theme when I was try to remove the ”powered by WordPress” on the bottom of the page. Thanks so much!

You can download a fresh copy of your theme and then upload it using an FTP client.

I fixed it saving wp.config.php in ANSI instead of UTF-8…

If the plugin troubleshooting doesn’t fix the issue, then you should try replacing your current theme with a default twenty ten theme. The best way to do this is by backing up your theme folder. Then deleting the theme. WordPress will automatically fall back to the default theme.
My site was hacked! I just restored it! Thank you so much! Even though it looks ugly, it is not directed to others sites.
Very useful guide!
One question: When I go to Google and type, it still says, ”This site may be hacked.” What can I to remove this?
Thank you so much again!

i had the white screen of death caused by a plug in, i renamed the plugins after eventually deciphering enough tech language to set up an FTP client via filezilla.(i had to watch 6 very annoying youtube videos to get there) Still only the admin log in box but nothing else. Came here, deleted the theme as directed and now even the log in box is gone. A years worth of work on my site gone, both page and my will are broken. any ’idiots set by step’ advice welcome x
erm3nda
For little bucks i can fix your site, sure.
I had no enough time to ”decypher” tech language. It’s is time consumption. Fix things is faster
If you really add worth to your website, consider that ”repairing” a kind of issue you can pay for get rid of.
Analogy of cars should be like: Your car do not cost only the 10.000 initial cost, it cost to you the fuel, tires and other things, like paint, repair etc.
Best of luck
