The older wording of the WordPress fatal error page.
WHAT IT MEANS
The same as the critical error message: a PHP fatal error occurred.
THE RECOVERY EMAIL
WordPress sends one to the administrator address with a link that logs you in with the offending plugin disabled.
Check your email, including spam, before anything else.
IF YOU CANNOT USE THE EMAIL
Enable debug logging in wp-config.php and read wp-content/debug.log.
Or check cPanel > Metrics > Errors, which frequently has the entry already.
THE USUAL CAUSES
A plugin or theme incompatible with the current PHP version A plugin updated to a version that conflicts with another Memory exhausted An edit that introduced a syntax error
REGAINING ACCESS
Rename wp-content/plugins in File Manager to disable everything.
If the site returns, rename it back and disable plugins individually.
AFTER A PHP VERSION CHANGE
Switch back to the previous version in cPanel > MultiPHP Manager, then update the responsible component before trying again.
