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.

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

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!!

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.

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!
Thanks,

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
