Hi,
Yesterday, Updated to OJS 3.3.0.4
Php: 7.4

Found the php fatal error in the following place: lib/pkp/classes/oai/error_log

Stack trace:

  thrown in /home/seisense/journal.seisense.com/lib/pkp/classes/oai/OAI.inc.php on line 24

Does anyone have the idea? what is this, what caused this error?
Thanks
