WordPress caught a fatal error.
WHAT IT MEANS
A PHP fatal error occurred. WordPress shows this rather than a blank page.
FIRST, CHECK YOUR EMAIL
WordPress sends a recovery email to the administrator address, containing a link that logs you in with the offending plugin disabled.
That is the fastest route back, and most people do not know it exists.
IF THE EMAIL DID NOT ARRIVE
The administrator address may be wrong, or mail may be failing, which is common on sites without SMTP configured.
ENABLE DEBUG LOGGING
Add to wp-config.php:
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);Reproduce, then read wp-content/debug.log.
Or check cPanel > Metrics > Errors.
DISABLE PLUGINS WITHOUT ACCESS
Rename wp-content/plugins to plugins-off in File Manager. All plugins deactivate.
Rename it back and disable individually to find the culprit.
SWITCH THEME
Rename the active theme's directory. WordPress falls back to a default.
