User Management not possible - an error occured

Nextcloud version 16.01
Operating system and version hosted_service
PHPMyAdmin possiple, command line not possible

Facing a problem in user management.
On my 1&1 hosted nextcloud are only to users.
1 User is an admin, the other a simple user.

But users are not displayed.

I can not create new user, I can not create new user groups.

On every reload within user management an error is displayed (see screenshot, top middle)

Sharing files, calenders, etc. between those 2 users works fine.
Login works fine.

Seems to me that something in the user management got messed up during the last updates with the online updater.

I would like to fix the problem without reinstalling.

Help is welcome :wink:

Try to clear the browser cache and try again. I realized that a problem as I update to NC 16.0.4 and this was the recommended solution for the problem.

Could not solve the problem by clearing the cache.

With NC17 I did a total reinstall. Everything was fine at the start. After I installed 2-Factor-auth with TOTP it started again. I activated log level 0 and that showed the following:

Is there anybody who could give me hint???

I invastigated a little further TOTP seems to be not the problem.

But opcache is activated and i found a very old problem, where
opcache.save_comments=1 needs to be set.

Which I have done.
But I do still have the problem.

Any help on this topic?
