to solve this issue
change - define('_PS_MODE_DEV_', false);
to - define('_PS_MODE_DEV_', true);
then find error.
example "Fatal error: Uncaught exception 'ReflectionException' with message 'Class ddressController does not exist' in"
the red text is the file missing,maybe it was unintentionally rename or you backup the original file and rename it like "AddressController_backup" on the same directory.
The solution is to remove the backup file and place it outside the controller also check if the controllers have correct file names.
Hope it helps
