A tela branca da morte pode ser o pior pesadelo de um proprietário de site. Esse erro frustrante do WordPress deixa você olhando para uma página em branco, sem oferecer nenhuma pista sobre o que deu errado.
Para piorar a situação, esse erro comum do WordPress às vezes pode afetar partes específicas do seu site, como a área de administração ou postagens individuais.
Por exemplo, vimos a tela branca da morte dentro da área de administração do WordPress enquanto todo o resto estava funcionando bem. Em outros casos, só a vimos ao visualizar uma postagem específica.
Entender as causas básicas desse erro é a primeira etapa para encontrar uma solução. Este guia abordará algumas soluções para corrigir a tela branca da morte e fornecerá etapas práticas para restaurar a funcionalidade do seu site.
Observação: antes de fazer qualquer alteração em seu site, certifique-se de ter um backup do site do WordPress. Se você não tiver acesso à área de administração, consulte nosso guia sobre como criar manualmente um backup do banco de dados do WordPress.
Por que você vê a tela branca da morte no WordPress?
Na maioria das vezes, quando você vê uma tela branca da morte ao tentar visitar seu site do WordPress, isso significa que um script em seu site esgotou o limite de memória.
O script que não responde é eliminado pelo servidor de hospedagem do WordPress ou simplesmente atinge o tempo limite. É por isso que nenhuma mensagem de erro real é gerada, e você vê apenas uma tela branca em branco.
No entanto, às vezes, você pode ver uma mensagem de erro.
Por exemplo, você pode ver uma mensagem de erro crítico em vez de uma página em branco.
Não importa se você está vendo uma tela em branco ou a mensagem “Houve um erro crítico no seu site”, o erro é o mesmo.
Esse erro também pode ocorrer devido a um tema ou plug-in mal codificado instalado em seu site. Às vezes, isso pode ocorrer se houver um problema com seu servidor de hospedagem na Web.
Como o erro de tela branca pode ser causado por vários fatores, é necessária uma solução de problemas metódica para corrigi-lo. Aqui estão as etapas que você deve tentar:
- 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 em vídeo
Se você preferir instruções por escrito, continue lendo.
1. Verifique se o problema ocorre em seus outros sites
Se você tiver outros sites WordPress instalados na mesma conta de hospedagem, comece verificando se o problema também está ocorrendo em outros sites.
Se for, esse é um forte indicador de que há algo errado com seu serviço de hospedagem WordPress. Esse pode ser um problema temporário que afeta o serviço e você precisa entrar em contato com o suporte para obter mais ajuda.
Por outro lado, se o problema estiver ocorrendo somente em um site ou em uma parte específica desse site, você saberá que o problema está nesse site específico.
2. Corrigir o erro de tela branca com o modo de recuperação do WordPress
Se o erro da tela branca da morte for causado por um plug-in ou tema do WordPress, o WordPress poderá detectá-lo.
O novo recurso de proteção contra erros fatais introduzido no WordPress 5.2 pode, às vezes, detectar o erro, de modo que talvez você nem veja uma tela branca. Em vez disso, você verá uma mensagem informando que o site está com dificuldades técnicas.
O WordPress também enviará um e-mail sobre o problema para seu endereço de e-mail de administrador.
O e-mail terá o assunto “Seu site está passando por um problema técnico”.
Essa mensagem de e-mail indicará o plug-in ou o tema que está causando o erro e também conterá um link especial.
Esse link permitirá que você faça login no modo de recuperação do WordPress e desative o plug-in com defeito.
No entanto, se estiver vendo a tela branca da morte sem nenhuma opção de e-mail ou modo de recuperação, será necessário corrigir o erro manualmente.
3. Aumentar o limite de memória
Normalmente, esse erro ocorre porque um script esgotou a memória do servidor da Web e foi encerrado no meio do processo.
Para corrigir isso, você precisa aumentar a memória PHP disponível para o WordPress. Isso permitirá que o script use mais memória para concluir o trabalho que deveria fazer.
Você precisará editar o arquivo wp-config.php em seu site do WordPress ou usar um plug-in de snippet de código como o WPCode.
Você pode seguir as instruções em nosso tutorial sobre como aumentar a memória PHP no WordPress.
4. Corrija o erro de tela branca desativando todos os plug-ins
Se o aumento do limite de memória do PHP não ajudar, ou se você tiver um limite de memória alto, como 256M ou 512M, será necessário iniciar a solução de problemas.
Em nossa experiência de solução de problemas, sempre descobrimos que o problema está em um plug-in específico ou em um tema. Vamos em frente e desativar todos os plug-ins.
Se ainda puder acessar o painel de administração do WordPress, basta ir para a página Plugins ” Plugins instalados. Selecione todos os plug-ins instalados e, em seguida, selecione “Deactivate” (Desativar) no menu suspenso “Bulk actions” (Ações em massa).
No entanto, se você não tiver acesso à área de administração do WordPress, precisará desativar todos os plug-ins via FTP.
Primeiro, conecte-se ao seu site WordPress usando um cliente FTP ou o gerenciador de arquivos do seu provedor de hospedagem. Depois de conectado, vá para a pasta wp-content, onde você verá a pasta plugins.
Agora, você precisa clicar com o botão direito do mouse na pasta de plug-ins e selecionar “Renomear”. Você pode renomear a pasta de plug-ins para “plugins-deactivated”.
O WordPress procura uma pasta chamada plugins para carregar todos os plugins. Quando não consegue encontrar a pasta, ele simplesmente desativa todos os plug-ins.
Se isso corrigir o problema, ative um plug-in de cada vez para descobrir a causa do problema. Quando encontrar o plug-in que está causando o problema, você poderá substituí-lo por um alternativo ou relatar o problema aos autores do plug-in.
5. Ativar o tema padrão
Se a solução de problemas do plug-in não resolver o problema, tente substituir o tema ativo por um tema padrão.
Primeiro, conecte-se ao seu site usando um cliente FTP e vá para a pasta /wp-content/themes/. Ela contém todos os temas instalados em seu site.
Clique com o botão direito do mouse para selecionar o tema atual do WordPress e baixá-lo para o computador como um backup.
Em seguida, você precisa excluir o tema atual do seu site.
Basta clicar com o botão direito do mouse na pasta do tema e selecionar “Excluir”. Seu cliente FTP excluirá o tema do seu site.
Agora, se você tiver um tema padrão do WordPress como (Twenty Twenty-Two ou Twenty Twenty-Three) instalado em seu site, o WordPress começará a usá-lo automaticamente como tema padrão.
No entanto, se você não tiver um tema padrão instalado, precisará instalá-lo manualmente usando o FTP.
Se isso corrigir o problema, você deverá examinar o arquivo functions.php do tema. Se houver espaços extras na parte inferior do arquivo, você precisará removê-los e, às vezes, isso resolve o problema.
Se você estiver usando uma função mal codificada no arquivo functions.php do seu tema, isso também poderá causar o erro de tela branca da morte.
Considere a possibilidade de baixar uma nova cópia do tema a partir da fonte e instalá-la manualmente usando FTP.
6. Ativar o modo de depuração para detectar erros no WordPress
Se nada tiver ajudado até agora, a próxima etapa é ativar a depuração no WordPress. Isso manterá registros de erros que lhe permitirão ver que tipo de erros estão sendo emitidos.
Basta adicionar o seguinte código ao seu arquivowp-config.php:
define( 'WP_DEBUG', true);
define( 'WP_DEBUG_LOG', true );
Depois de adicionar isso, a tela em branco passará a ter erros, avisos e notificações. Eles podem ajudá-lo a determinar a causa raiz.
Se não houver nenhum erro, talvez seja melhor verificar o registro de depuração.
Basta acessar a pasta wp-content em seu site usando um cliente FTP. Lá, você encontrará um novo arquivo debug.log que contém um registro de todos os erros, avisos e advertências.
7. Limpar o cache do WordPress
Às vezes, você pode ter acesso ao back-end, mas o front-end do site apresenta a tela branca da morte.
Isso pode acontecer por causa de um plugin de cache. Nesse caso, basta esvaziar o cache do WordPress.
Consulte nosso guia sobre como limpar o cache no WordPress para obter instruções detalhadas.
8. Corrigir o erro de tela branca para artigos mais longos
Se você tiver uma tela branca da morte somente em uma postagem ou página muito longa, esse método poderá funcionar.
Esse truque basicamente aumenta a capacidade de processamento de texto do PHP, aumentando o limite de recursão e retrocesso. Você pode colar o código a seguir em seu arquivo wp-config.php:
/** Trick for long posts */
ini_set('pcre.recursion_limit',20000000);
ini_set('pcre.backtrack_limit',10000000);
Entendemos que esse é um erro muito frustrante e esperamos que um dos truques acima tenha corrigido o problema para você.
Talvez você também queira ver nosso guia de solução de problemas do WordPress, que ensina as etapas que você deve seguir para detectar e corrigir problemas do WordPress por conta própria, ou nossa lista dos problemas mais comuns do editor de blocos do WordPress e como corrigi-los.

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.

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
