La pantalla blanca de la muerte puede ser la peor pesadilla del propietario de un sitio web. Este frustrante error de WordPress te deja mirando una página en blanco, sin ofrecerte ninguna pista acerca de lo que ha ido mal.
Para empeorar las cosas, este error común de WordPress a veces puede afectar a partes específicas de su sitio web, como el área de administrador / administración o entradas individuales.
Por ejemplo, hemos visto la pantalla blanca de la muerte dentro del área de administración de WordPress mientras todo lo demás funcionaba correctamente. En otros casos, solo lo hemos visto al visualizar una entrada concreta.
Entender las causas de este error es el primer paso para encontrar una solución. En esta guía se describen algunas soluciones para corregir la pantalla blanca de la muerte y se ofrecen pasos prácticos para restaurar la funcionalidad de su sitio web.
Nota: Antes de realizar cualquier cambio en su sitio, asegúrese de tener una copia de seguridad de su sitio WordPress. Si no tiene acceso al área de administrador, consulte nuestra guía sobre cómo crear manualmente una copia de seguridad de la base de datos de WordPress.
¿Por qué aparece la pantalla blanca de la muerte en WordPress?
La mayoría de las veces, cuando ve una pantalla blanca de la muerte al intentar visitar su sitio web de WordPress, significa que una secuencia de comandos en su sitio web agotado el límite de memoria.
El script que no responde es eliminado por el servidor de alojamiento de WordPress o simplemente se agota el tiempo de espera. Por este motivo, no se genera ningún mensaje de error y sólo se ve una pantalla en blanco.
Sin embargo, a veces puede aparecer un mensaje de error.
Por ejemplo, es posible que aparezca un mensaje de error crítico en lugar de una página en blanco.
Tanto si aparece una pantalla en blanco como el mensaje “Se ha producido un error crítico en su sitio web”, se trata del mismo error.
Este error también puede deberse a un tema o plugin mal codificado instalado en su sitio. A veces, puede ocurrir si hay un problema con el servidor de alojamiento web.
Dado que el error de la pantalla blanca puede ser causado por cualquier número de cosas, se requiere diagnosticar metódicamente para corregirlo. Estos son los pasos que debe probar:
- 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
Tutorial en vídeo
Si prefiere instrucciones escritas, siga leyendo.
1. Marque / compruebe si el problema se produce en sus otros sitios web
Si tiene otros sitios de WordPress instalados en la misma cuenta de alojamiento, empiece por marcar / comprobar si el problema se produce también en otros sitios.
Si es así, entonces eso es un fuerte indicador de que algo está mal con su servicio de alojamiento de WordPress. Podría tratarse de un problema / conflicto / incidencia temporal que afecta a su servicio, por lo que debes ponerte en contacto con su servicio de soporte para obtener más ayuda.
Por otro lado, si el problema solo se produce en un sitio web o en una parte específica de ese sitio, entonces sabrá que el problema está en ese sitio web en concreto.
2. Corregir el error de pantalla en blanco con el modo de recuperación de WordPress
Si el error de pantalla blanca de la muerte es causado por un plugin o tema de WordPress, entonces WordPress puede ser capaz de detectarlo.
La nueva característica de protección contra errores fatales introducida en WordPress 5.2 a veces puede detectar el error, por lo que es posible que ni siquiera vea una pantalla blanca. En su lugar, verás un mensaje que indica que el sitio está teniendo dificultades técnicas.
WordPress también enviará un correo electrónico acerca del problema a su dirección de correo electrónico de administrador.
El asunto del correo electrónico será “Su sitio está experimentando un conflicto / incidencia técnica”.
Este mensaje de correo electrónico indicará el plugin o tema causante del error, y también contendrá un enlace especial.
Este enlace le permitirá acceder al modo de recuperación de WordPress y desactivar el plugin defectuoso.
Sin embargo, si usted está viendo la pantalla blanca de la muerte sin correo electrónico o la opción de modo de recuperación, entonces usted necesita para corregir manualmente el error.
3. Aumentar el límite de memoria
Normalmente, este error se produce porque un script ha agotado la memoria de su servidor web y se ha salido en medio.
Para corregir esto, necesita aumentar la memoria PHP disponible para WordPress. Esto permitirá que el script utilice más memoria para terminar el trabajo que se supone que debe hacer.
Deberá editar el archivo wp-config.php de su sitio de WordPress o utilizar un plugin de fragmentos de código como WPCode.
Puede seguir las instrucciones de nuestro tutorial sobre cómo aumentar la memoria PHP en WordPress.
4. Corregir el error de pantalla blanca desactivando todos los plugins.
Si aumentar el límite de memoria PHP no ayudó, o si tiene un límite de memoria alto, como 256M o 512M, entonces necesita comenzar a diagnosticar.
En nuestra experiencia diagnosticando esta incidencia, siempre hemos encontrado que el problema está relacionado con un plugin específico o con un tema. Vamos a desactivar todos los plugins.
Si todavía puede acceder al escritorio de administrador de WordPress, puede ir a la página Plugins ” Plugins instalados. Seleccione todos los plugins instalados y, a continuación, seleccione “Desactivar” en el menú desplegable “Acciones por lotes / en lotes”.
Sin embargo, si no tiene acceso al área de administrador de WordPress, tendrá que desactivar todos los plugins mediante FTP.
En primer lugar, conéctese a su sitio de WordPress utilizando un cliente FTP o el gestor de archivos de su proveedor de alojamiento. Una vez conectado, vaya a la carpeta wp-content, donde verá la carpeta plugins.
Ahora, tienes que hacer clic con el botón derecho del ratón en la carpeta plugins y luego seleccionar ‘Renombrar’. Puede cambiar el nombre de la carpeta de plugins a ‘plugins-deactivated’.
WordPress busca una carpeta llamada plugins para cargar todos los plugins. Cuando no encuentra la carpeta, simplemente desactiva todos los plugins.
Si esto corrige el problema, active un plugin cada vez para llegar al fondo de la cuestión. Una vez que encuentres el plugin que causa el problema, puedes sustituirlo por uno alternativo o informar de la incidencia a los autores de los plugins.
5. Activar el tema por defecto
Si la solución de problemas de plugins no corrige el problema, entonces usted debe tratar de reemplazar su tema activo con un tema por defecto.
En primer lugar, conéctese a su sitio web mediante un cliente FTP y vaya a la carpeta /wp-content/themes/. Contiene todos los temas instalados en su sitio web.
Haga clic con el botón derecho para seleccionar su tema actual de WordPress y descárguelo a su ordenador como copia de seguridad.
A continuación, debe borrar el tema actual de su sitio web.
Simplemente haz clic con el botón derecho del ratón en la carpeta del tema y selecciona “Borrar”. Tu cliente FTP borrará el tema de tu sitio web.
Ahora, si tienes un tema por defecto de WordPress como (Twenty Twenty-Two o Twenty Twenty-Three) instalado en tu sitio web, entonces WordPress automáticamente empezará a usarlo como tema por defecto.
Sin embargo, si no tiene instalado un tema por defecto, deberá instalarlo manualmente mediante FTP.
Si esto corrige el problema, entonces usted debe buscar en el archivo functions. php de su tema. Si hay espacios adicionales en la parte inferior del archivo, entonces usted necesita para quitar esos, ya veces que corrige el problema.
Si está utilizando una función mal codificada en el archivo functions. php de su tema, también puede causar el error de pantalla blanca de la muerte.
Considere la posibilidad de descargar una copia nueva del tema desde su fuente e instalarla manualmente mediante FTP.
6. Activar el modo depuración para detectar errores en WordPress
Si nada ha ayudado hasta ahora, el siguiente paso es activar la depuración en WordPress. Esto mantendrá los registros de errores que le permiten ver qué tipo de errores se están emitiendo.
Simplemente añada el siguiente código a su archivowp-config.php:
define( 'WP_DEBUG', true);
define( 'WP_DEBUG_LOG', true );
Una vez añadido esto, la pantalla en blanco tendrá ahora errores, advertencias y avisos. Estos pueden ser capaces de ayudarle a determinar la causa raíz.
Si no ve ningún error, puede que quiera comprobar el registro de depuración.
Simplemente visite la carpeta wp-content en su sitio web utilizando un cliente FTP. Allí encontrará un nuevo archivo debug.log que contiene un registro de todos los errores, avisos y advertencias.
7. Vaciar la caché de WordPress
A veces, usted puede tener acceso a la administración / escritorio, pero la parte frontal del sitio tiene la pantalla blanca de la muerte.
Esto puede ocurrir debido a un plugin de caché. En ese caso, solo tienes que vaciar la caché de WordPress.
Puede consultar nuestra guía sobre cómo vaciar la caché en WordPress para obtener instrucciones detalladas.
8. Corregir el error de pantalla blanca en los artículos más largos.
Si solo tienes una pantalla blanca de la muerte en una entrada o página muy larga, entonces este método podría funcionar.
Este truco básicamente incrementa la capacidad de procesamiento de texto de PHP aumentando el límite de recursión y retroceso. Puedes pegar el siguiente código en tu archivo wp-config.php:
/** Trick for long posts */
ini_set('pcre.recursion_limit',20000000);
ini_set('pcre.backtrack_limit',10000000);
Entendemos que se trata de un error muy frustrante, y esperamos que alguno de los trucos anteriores te haya corregido el problema.
También puede consultar nuestra guía práctica para diagnosticar problemas en WordPress, que le enseña los pasos que debe seguir para detectar y solucionar por sí mismo los problemas de WordPress, o nuestra lista de los problemas más comunes del editor de bloques de WordPress y cómo solucionarlos.

I solved it…
I tried those:
define(‘WP_MEMORY_LIMIT’, ’64M’);
Change Plugins name
Check white spaces
Increase memory
Change Theme
Upload new wp-admin
And everything related to plugins
Finally I downloaded my wp-config using FTP. Opened it with notepad++ and save it again with the encoding utf-8… It was utf-8 BOM.
Linda
My page does not work! it shows SERVER ERROR 500. and i am unable to log into the admin
Andreas
Thank you, changing the SiteURL did the job.
What a weird bug…
Girish
I am telling you i cannot access my wp-admin page how i am suppose to disable plugin and change the theme.
WPBeginner Support
Simply connect to your website using an FTP client and rename the plugins folder to plugins-old. This will deactivate your plugins directory.

This is one of the most extensive guides I found so far – with easy tutorials on how to solve it. I like it!
I’m actually only missing one thing causing WSOD and that is extra spaces in the code, usually in functions.php, header.php, single.php etc. I’ve found this error causing most of the white screens I’ve resolved. The extra spaces are usually at the end of the file, after a closing ?>, used instead of tabs and on line breaks (empty rows).
Thanks for a great guide.

After some changes (failures !!) in the code of a plugin did the famous White wp screen with the following message “Parse error: syntax error, unexpected ‘the’ (T_STRING) in / home / velafati / public_html / wp-content /plugins/woocommerce/includes/class-wc-countries.php on line 436 ”
How to know where the problem had been entered in the file “class-wc-countries.php” through cpanel and replace all the code for the original code (had recorded the original code in Notepad). The problem is that even after upgrading to the problem folder remains, what should I do?

Hi Guys,
I got some white space page issue in our wordpress page and did below troubleshooting but still no luck. It’s also weird that I don’t get any error.log that’s why it’s kinda hard to know the exact issue. Any help would be very much appreciated. Thanks Guys.
Troubleshooting made:
Disabled all plugins

Sabina
I fixed it! It was a plug in. Do NOT update the Yuzo plug in if you currently have it!
Sabina
Please help!!! I think I’m gonna die! I get the white screen and I cannot get to my admin page. Everything is white :(:(:( Please, please tell me step by step what I should do not to mess things even more!
Thank you!
Naomi
I experienced the white screen of death tonight and I couldn’t access my login, website, or any of the pages. I fixed it by going to hosting site and pulling up the file manager. I was able to edit the code I had misplaced through the files on the hosting site and then my site came back up!
Lee Binder
In our case it was problems with cron, either WP cron or the server’s cron service. “Fixed”/ worked-around with the WP Delay Cron Plugin
Thomas
Hi all, I have the same error but cant even access the login page for my site! Any ideas on what i could do? Thanks!
calvin
I had the same issue, it was a plugin. went to the cpanel, then file manager, public html folder and on right side, right click on “error log” to view error. Plugin causing error was renamed and whala… I could get to the dashboard.
Hope this helps you and others!
Bomi
This should be the firt option if you only have access to FTP, it will tell you exactly which file is messed up. Thanks.
error_reporting(E_ALL); ini_set(‘display_errors’, 1);
define( ‘WP_DEBUG’, true);
Kay
I get an error message that says Site can nor be accessed. Disconnect site. When I click on admin the screen goes white. Please help!
Andy
I had this problem with my installation (white screen only on WP-admin. I eventually solved it by using the debug tools in the browser (hit F12 in most browsers). Using the console view in the debug I could see that there was some sort of error in a frame that was being used.
I haven’t got to the bottom of this yet but I was able to access the login page and access wp-admin by switching my re-directed URL for the raw IP address. I expect I have mucked up the re-direct in some way but I’m just relieved to have fixed it to be honest!
Hope this helps someone else!
Jacob J
The error reporting thing solved my problem. Knew I had a misplaced code in there somewhere, and those few lines in the config file showed me where. Thanks a lot. /Jacob
dinesh Kumar
thanks a lot i found error wp_debug already defined and resolved this error and also installed new theme now my site is opening but i can’t access my admin page when i type admin url it’s showing it’s not redirecting properly
Kaley Basham
Ok, so I replaced the theme by replacing the current_theme, template and stylesheet in PHPmyAdmin to twentyeleven and it fixed the white screen of death issue. Now I checked my functions.php document and I had no extra spaces in the end.
So now what?!?!??? Thanks for any help!!
WPBeginner Support
Try downloading a fresh copy of your WordPress theme.

THANK YOU SO MUCH! It was one of the Whatsapp Plug-ins which was causing an issue. I can now sleep peacefully tonight – my site is up and running again.
Timothy
Thanks for this. I ran the error code and found a malicious file. link-template.suspected.
I removed the file and replaced it with a new one that I had downloaded and that fixed.
All this after going through every other thing to no avail.
Replacing the bad file got things back.
stef
Thanks, debug mode works great i could find the faulty php script
Hugo
The blank screen can also be caused by using the wrong version of php. PHP 5.2 has cause me trouble in the past, changing to 5.4 fixed it. Be sure to check this if all else fails.
Kelly
Another vote for PHP version. I tried almost everything and was about to replace the theme when I gave this a go. Upgraded to 5.5 and like magic, it was fixed! Thanks Hugo.
Bobby
Coded my own theme and had blank screen when trying to update posts and pages, deleting spaces at the bottom of my functions file solved the issue!
Jonas Holm
I went through all the above steps without succes. I downgraded PHP 5.6 to 5.3 on my providers PHP-admin-page. That solved my problem.
Grace
I’ve read through all of this but sadly my problem is that I can’t even log on anymore – I got the white screen of death but it says that when you try to go onto my page and when I even try to go to the Wordpress dashboard (via Godaddy). I now have absolutely no way to log on to my wordpress – not sure what to do!
Tawanda
I just fixed this problem, it was a caching issue. If you go to your wp-config.php file then remove the code just above the define(‘DB_NAME’, ‘your_db_name’);
This should work, as it worked for me
Nhan Nguyen
It worked fine for me. Many thanks.
jake
No code there
Jan Fallon
I had the WP CACHE code in my wp-config.php file – just above the define(‘DB_NAME’, ‘your_db_name’); as stated by TAWANDA and removed it – and so far my home page, which was completely white, is holding!
I could log in via admin, and saw all my content, but at the URL the home page was white.
FIXED with crossed fingers!
Many thanks wpbeginner crowd!
Jan
Juan Jose Hernandez Cruz
I cannot even log in I have a blank screen. what do you suggest please help
LaQuata
I had the same issue and I did the replacing the theme. This work for me.
Sam
Had this same problem when updating my wordpress plug-ins. I accidently clicked on a link while a couple of plug-ins were updating. The site was okay but could not get into the admin section. Log-in was blank. After reading this article tried changing the plug-ins file name. Admin was still blank and site now wouldn’t load. Change the plug-in folder back to its correct name.
I didn’t delete the theme since this would be a headache to ressurect, I have text widget areas with code and all of this would delete. Instead skipped to the error fix, under “other suggestions” and placed the script in the wp-config.php file. An error popped up for a “google analytics plug-in”. I ftp’d in and changed the name of the folder for that plug-in which fixed the problem.
I could now log-in to the admin area. I then checked the name of the plug-in and found the plug-in through the wordpress “new plug-in” feature. Loaded it in then deleted it. Did this to clear it out of the database. Haven’t reinstalled it yet. Enough headaches for one day
Hope this helps someone…
Paola
I have a problem inside my WordPress admin panel. I can get in but then I get the
white screen of death when I try to edit comments and the like and I cannot
seem to get to use my dashboard. I have tried deactivating plugins and also
re-installing a fresh copy of WordPress but this didn’t seem to help. I also tried replacing my
current theme with a default twenty ten theme but that seemed difficult and I
am not sure I was able to do so. The article also suggested
using the WordPress debug function to see what type of errors are being
outputted. I did manage to add the suggested code in my wp-config.php file and
I got some messages but I am not very good with code so I don’t really
understand what is being said. Any suggestions?
Henry
did you try increase the memory by
define(‘WP_MEMORY_LIMIT’, ‘128M’); in wp-config
Pat
I tried everything listed on this post to no avail. I finally found the
fix for my situation! My problem was related to an older versions of
WP: 3.3.1.
I looked at the error_log file in the wp-admin
directory and saw the following error: “PHP Fatal error: Access to
undeclared static property: WP_Screen::$this in
/home2/bellex/public_html/wp-admin/includes/screen.php on line 706”
I had things setup using the WordPress debug function described above.
Anyhow this error led me to a website that directed me on how to alter the screen.php file. See this site for details:

Like Nese, this simply explained solution was the answer, Thank you, thank you!

Remove the extra spaces at the bottom of function.php save my life! Many Thanks!
WPBeginner Staff
Yes you can delete and reinstall a theme. However, you will also loose any other customizations you made to the theme.
Veronca
Thanks a lot for the help. I add some code to my Cron Job. I deactivated all my network plugins and asked hostgator to increase my memory. The last thing I need is the white screen of death during production. My site has been down all day, but now its back up. THANKS AGAIN!!
Bboo
Can I just delete the the entire theme file. And re-install it? Will that fix the white screen? I was working on the .php, but now looking at the files, i have NO IDEA which one i was in!!
Nese
Thank you so much. This post and this comment solved it for me.
You’ve made my day.
Bboo
How is everyone having to option to see pages?? When I login I ONLY see BLANK PAGE. No options, no links, no files. NOTHING!! Someone please help!!
Eduardo Flores
A month later but… Maybe you have to check your files via FTP
WPBeginner Staff
You can use an FTP client to access files on your web server. Locate the file you edited earlier and undo the changes you made to it.
You can also use the File Manager in your web hosting account’s cPanel dashboard.
WPBeginner Staff
You can use the File Manager from your cPanel account to edit the php file.
Morgan
I fixed my white screen of death by deleting the code I had written just before it crashed. I did that through the Bluehost file manager. I found my website file (the wordpress install file), then went into wp content, found the theme I was using, then opened the functions file (to fix the theme’s function .php file).
Piotr
Hi there, I am having the same problem and tried literally everything
how did you fix the functions file?
Laura
Thanks!!! That’s exactly what I had to do – thanks for spelling it all out for me!
Morgan
I just found this article about how to do things on the site through Bluehost. But since I know it’s not a plugin problem; I know it’s my .php file, is there something else I can do? Is there an outside way to access my .php file (via Bluehost)? I’m sorry but I am freaking out over here.

Morgan
Hi, thank you for telling me what this is. I tried putting in the code from your how-to-avoid-no-thumbnail-issue-while-sharing-post-on-facebook post, and I’m sure I’ve corrupted a file doing something wrong. I can’t get anywhere, it’s all white. How do I disable plugins or go to a default theme this way? I’m going to lose so much work, aren’t I?!???
Mark
Rather than deleting a potentially broken theme, you can just rename it. WordPress will still fall back to a default and it saves the bother of backing up & deleting.
imLOST
I had extra spaces at the bottom of my functions.php file.
After the closing ?> tag. Cleared them up and all was good!
Hasan Shahzad
I have got it fixed by renaming plugins folder to plugin, Wordpress deactivated my all plugins and I was able to access WP-Admin, I tried to activate all plugins manually, however one plugin returned fatal error while activating itself “(include_path=’.:/usr/lib/php:/usr/local/lib/php’)” Then I got it, that plugin was creating mess. Now my blog works fine.
