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.

After I cleared my cache, it fixed. Why wasn’t this put into the article?
Thinking I was going to have to get into code when it was a simple fix is silly.
Please clear your browser cache first before you try anything else.

It is very rare that your caching would cause that specific issue but we’re glad that clearing the cache worked for you.

Your article says deactivate plugins then goes on to talk about FTP – you don’t say what to do after I’ve deactivated the plugins… unless I missed it.

If the error disappears once the plugins are disabled, you would then know that the error is caused by a plugin and you would need to find the specific plugin.

I got the white screen. I had just made changes to my child theme functions php, so I knew what the problem was. I followed your steps to my wp-content /themes, Then I did this…and it was easy. Right click on child theme, topen, then functions php file, deleted what I did. Saved changes. Checked if I could enter wp-admin, and all was good. I did not have to hassle with changing themes or plugins on/off. I use your site often, and I hope you test this option, and put it as a simple solution.
Thanks for your helpful site.

In my case, the security plugin had temporarily blocked me because I entered the password incorrectly too many times… I forgot I changed it. I was seeing a white screen with the word “error” in the upper left hand corner.
To resolve this, I logged into the database and removed myself from the lockout table.

We are two administrators, and the white screen of death is only affecting one of us — and not all the time. Any suggestions for this? Thanks.
LIAM
I am having a similar problem where I have had this problem reported by other users, but I do not experience it myself. I am an Administrator, but the people reporting the problem are not. I made a new account set up as Admin for someone who had this issue, and the WSOD did not affect them when using their new account. Because the problem is not universal and seems to be resolvable by changing the profile admin level, it makes me think that it is not the plugins or theme that is causing the issue. Any help would be greatly appreciated.
WPBeginner Support
Hi Liam,
Many themes and plugins and trigger different functions based on user roles. Here is how you can test.
1. Create a new user account with a user account that usually sees the WOD.
2. Disable all your plugins.
3. Visit your website with that user account in a different browser
4. Reactivate your WordPress plugins one by one until the user account is able to see the WOD again.
This way you will be able to figure out exactly which pluhgin is causing the issue. For checking your theme switch to a default theme and see if this solves the issue.
Administrador
LIAM
Hi there,
Thanks for the response and the suggestions. It sounds like a good way to start.
Just to clarify, with Step 1. are you saying that I should duplicate an account that currently experiences this problem OR that I should use an account that sees the WSOD to make a new account for testing?
Can’t see why it would be the second option, but I just thought I’d check as the wording was a bit confusing.
WPBeginner Support
Hi Liam,
You should create a new user account with the same user role as the one seeing WOD on your site. For example, if a user account with author user role is seeing the error, then create a new dummy user account with author user role for testing.

Hello there!
I have a wordpress blog and have had my first experience of the famous White Screen of Death or at least I think so since the screen is white with only the WP logo. This started when I tried to approve a comment and the button didn´t respond after which I realized that I couldn´t access my admin controls, my stats or any personal controls.
Since I have no experience what so ever of programming or coding and can´t even access the ordinary support pages without seeing this wsod, I am helpless and would soo appreciate if anyone of you computing wizards could help in any way?

I have had the ‘white screen of death’ for for weeks. I’ve had to store all of my what-would-be blog posts as notes in my device until I could find the solution. Nothing worked. I was about to create new blogs elsewhere when something struck me. I always browse in private mode. This never bothered wordpress in the past (years), but it occasionally will be the cause on other websites.
After all this time… I turned off private browsing cleaned cookies for safe measure, and…. logged in just fine.

Had the WSOD problem when I updated my website theme. I had no website or admin login tried numerous fixes but to no avail.
The solution that worked for me was to download the latest version of my theme. I renamed previous non functioning theme to themename_old and then uploaded via ftp the replacement theme zip file and extracted the contents and it worked.
The above will work if you have access to cpanel or support at your serverhost can set up and supply you the ftp username, password.
Good luck
