OJS 3.3.0.8 OAI Schnittstelle funktioniert nicht / List Records führt zu Blank Page Fehler 500

Liebe Community,

wenn ich über die oai Schnittstelle den Request “List Records” aufrufe, bekomme ich folgende Fehlermeldungen im error.log :

Hallo Frank,

solche Anfragen sind im englischsprachigen Forum besser aufgehoben, dort lesen auch die Mitarbeiter/innen von PKP bzw. die Entwickler/innen. Hier geht es um speziell deutsche Themen (DNB, VG Wort, Übersetzungen , Datenschutz …).

Ich habe auf einer unserer 3.3.0-8 Versionen geschaut, da funktioniert List Records.

Wir haben unter metadata aber auch kein mods34 Plugin bzw. es wird nicht versucht, dieses aufzurufen.
