⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.

Bug description

After upgrade to 30.0.9, Group Admins are not able to create new Accounts anymore.
If you click on "New Account" the Group "admin" is prefilled in "Member of the following groups" and the Group Admin is not able to delete this Group. Adding another Group results in the Error "Logged in account must be an admin, sub admin...".

Steps to reproduce

1. Create a group and an user with group admin rights for this group
2. Log in as this user and try to create a new user
3. The field "Member of the following groups" is prefilled with the group "admins"
4. Try to delete this group an add the group created under 1.
5. Try to create the new user with any other group

Expected behavior

Group Admins should be able to create new users in their own group.

Hi,
I can confirm that I’m also experiencing this issue on my Nextcloud instance (v30.0.9). As a regular user, I can no longer see any of the groups I manage as a group admin — the Groups section in Personal Settings is completely empty.
However, when logged in as an administrator, all groups and user memberships are still visible via the admin panel.

I can confirm the same behaviour with version 31.0.4.

I can confirm the same behaviour with version 30.0.10. in 15 instances.

I can also confirm it, my instance with version 30.0.10 has the same problem. Please fix it soon.

I can confirm the same behaviour with version 31.0.10. in 15 instances.

Should be 30.0.10?

Should be 30.0.10?

Of course your're right, typo, sorry.

I'm getting the same behavior on the 3 instances I've updated to 30.0.10. The only workaround I've found is to add the user to the admin group, but that exposes critical configurations on the instance that shouldn't be accessible by a non-technical user.
