Block members from starting new threads not working

[Macsee]

I would like a certain usergroup to be blocked from starting threads in a particular forum.

I have gone to the Admin CP > Forum & Moderators > Forum Permissions. For this forum and this user group I've set "Can Post Threads" to No.

But users from that usergroup are still able to create threads in this forum.

Is there some other setting somewhere that needs to be corrected?

I've discovered this does work for some members in the usergroup, but not others.

This usergroup is based on postcount. Members get promoted to this group on acquiring 5 posts. Members who move up to this usergroup from Registered Users seem to be blocked from creating new threads in this forum (as intended). Members who've been manually "demoted" to this user group seem to be immune and they can still create threads.

Why do the usergroup restrictions for a forum work only on some members and not others? This seem to be a vB bug. Can anyone confirm?

Do you use secondary usergroups? If a user belongs to more than one usergroup they will have the most permissions allowed by any group.

It's also possible for a user to have an "access mask" which gives them more permissions than their usergroup.

That's a good point and I should have mentioned that I don't use secondary usergroups. Every member has only a primary usergroup.

But you were correct on the other suggestion. For some reasons there are some access masks which I don't recall ever setting. And these access masks are giving users permissions on the forum I had blocked them from. I will go delete these access masks now.

Many thanks.
