WHAT IT MEANS
A fatal PHP error with error display disabled.
The server produced nothing.
WHAT TO DO
- Check the error log

THE COMMON CAUSES
A recent edit with a syntax error A plugin conflict Memory exhausted A missing file after an incomplete upload A PHP version incompatibility
WHAT TO TRY
If it started after an edit, restore your copy If it started after activating a plugin, deactivate it If it started after a version change, revert the version
DEACTIVATING PLUGINS WITHOUT ACCESS
Rename the plugins directory by FTP or File Manager.
That deactivates everything and usually restores access.
Rename it back, then deactivate individually to find the culprit.
