Go to Analyze Permissions, click the "Node Permissions" tab. Enter the username of an affected user and also select a forum where they can't edit their own posts.
Look down the list for:
Edit post by self
Time limit on editing/deleting own posts (minutes)
In the second column it will list the final value of the permission, and have a "Details" link. Click the "Details" link and screenshot all of that and post it here. That should tell us what has gone wrong.
Yes, I did some individual user permissions that I think I shoudln't have...might have made things difficult on myself there. I appreciate your help very much...
Another question...with regards to analyzing permissions, what does "content wide" mean? I am trying to set up a staff room section for conent contributors, blogs and the like, but for some reason it indicates content wide in the category and forum as revoked.
