Suddenly users cannot login freshly (already authenticated users have no problem and an Internal Server Error appears.
It’s always the same log line:
Error
Call to undefined method OCP\AppFramework\Http\Events\BeforeLoginTemplateRenderedEvent::isLoggedIn()
I mean the error makes sense.
There’s really not a lot to say about this. It’s in no relation to any update or change on the server. Apache2 logs expectedly show nothing.
