[CarlSchwan]

Can you test #1868?

[TP75]

@CarlSchwan Thanks for the prompt reply.

The test is running. So far so good.

I made the proposed changes taken from your a.m. fix and turned maintenance mode off again. However, the respective cron job is called once an hour only and I am unsure if the cron job may have changed in time. Will come back in 2 hours for further details of the test, I presume.

[TP75]

The fix holds as expected. No error messages in the logging.

@CarlSchwan THX

[TP75]

However, awaiting official 9.0.5 version or later of Group Folders App.

[h4knet]

I've the same issue.
I've tried the fix provided by @CarlSchwan ; I will update if the errors are still appearing.
