I am getting the following error when people try to edit their user profiles in the forum. Can someone help me out? One of the user used to be able to edit and now he can not.

OK, I have figured this out and I am not sure if this is a bug that has been fixed in a newer version or not. I am running 3.20.6 and I think release 3.20.8 is out.

Anyway, if a members selects to track a forum and then that forum is removed, the user can no longer edit their user settings since the forum is not there to ick the check box to track. I manually removed the tracking entries in both the Forum_TrackedForums and Forums_TrackedWhatsNew tables and the users can now see edit their settings.

If this is not fixed in a newer version, until it gets fixed, is there a way to stop users from being able to track forums. We dont add/remove forums that often but we do add new forums to discuss things and then pull them down when we are finished.
