Greetings,

After Upgrading to 2.9 my Users List is empty. There is no request to user_list_backend.php.
I tried Firefox and Google Chrome with cleared caches and both administrative themes.
The Groups List shows the users in their groups.
I am using my docker image from https://hub.docker.com/r/hg8496/piwigo/

Thanks
Christian
