The WordPress white screen of death or Blank screen is one of the most common WordPress errors. There is no error message, and you are locked out of WordPress, so it is very frustrating.
Why Do You See the White Screen of Death in WordPress?
1. The first reason is that a script on your website exhausted the memory limit.
2. If you have a high memory limit like 256M or 512M, then the issue is either with a specific plugin or a theme.
3. If the plugin troubleshooting doesn’t fix the issue, then you should try replacing your current theme with a default theme.
4. Sometimes, you may have access to the backend, but the front-end of the site has the white screen of death. This can happen because of a caching plugin.
How to solve it?
1. Usually, this error happens because a script has exhausted the memory and quit in the middle. To fix this, you need to increase PHP memory available to WordPress. This will allow the script to use more memory to finish the job it was supposed to do.
2. If increasing the memory limit did not help, or if you have a high memory limit like 256M or 512M, then the issue is either with a specific plugin or a theme.
Let’s go ahead and disable all the plugins. If you can still access the WordPress admin area, then you can simply go to Plugins » Installed Plugins page. Select all the installed plugins and then select ‘Deactivate’ under ‘Bulk Actions’ drop-down.
However, if you don’t have access to the WordPress admin area, then you will need to deactivate all plugins via FTP.
First, connect to your WordPress site using an FTP client. Once connected, go to the wp-content folder where you will see the ‘plugins’ folder.
3. If the plugin troubleshooting doesn’t fix the issue, then you should try replacing your current theme with a default theme.
4. Sometimes, you may have access to the backend, but the front-end of the site has the white screen of death. This can happen because of a caching plugin. Simply empty your cache. You need to visit Settings » WP Super Cache page and click on ‘Delete Cache’ button.
