Problem with Forums-Module
Hi,

we've tried to implement a forum, but we get the attached error...

what we've done yet:

- all forum tables are clear (forums_<....>)
- we created a new group
- on group edit => VIEW: all right, group is shown
- added one forum to group
- on GROUP edit => VIEW: the error is displayed
- on FORUM edit => VIEW: all is ok

The error is displayed too on site if we add a webpart to show forum groups...

ASPX-File path (on CMS-Desk): ..../CMSModules/Forums/Tools/Groups/Group_View.aspx?groupid=10

Whats wrong?
