Please help!!  I have a forum with a usergroup and access created for that user group.  The forum is connected to the user group, and my users have the box checked to have access to that user group.  When I go to the page where the forum is embedded, I can click on any post, and it takes me to the home page.  I have tried to check everything.  I've checked a few different users.  I can't find where the problem is!!

This is critical as this online course is using the forum for students to talk to each other and this is already the 2nd week of the course.   We had a forum last quarter that worked fine.  I have compared the settings and don't see a difference. 

Thanks - what is likely my issue?
