Advanced file manager (fileManager2.php) HTTP ERROR 500

Advanced file manager worked fine on installation (few days ago), did not touch anything on server
Today, trying to access Advanced file manager (fileManager2.php) i got HTTP ERROR 500

Restarted CWP, Apache & MySQL to check if they have any relation
None

Checked logfiles at \usr\local\cwpsrv\logs\error_log and found these lines:
