Weird: New Users can change thread title, old users not

[mybbz]

Hello,

I have a realy strange problem with my vb. I tried about 100 things and workarounds for this problem, without any success.

The problem: A user who is registered for a longer time, is not able to change the complete threadtitle. The user can edit their post/thread and of course its possible to change the title in the editor. But the title won't change on the forumview or in the top title of the thread, only on the smaler subtitle of the thread/posttitle the changes take affect. :down:

The weird thing is: If a new registered user does the same, its totaly working and the threadtitle is also changing in the forum view and on the top of the title, as it should be.:up:

There is no difference between the user groups, they are both in the group "registered users". So I think theres just something I don't know or I don't get right now. Whats the cause why old registered useres have other rights then new registered users, even if they're in the same group?!

Thanks for your help!
