At some point my forum completely stopped showing up for users that are logged in -- which obviously makes no sense because they need to log in. This is true in the back end as well. When I am logged in as the admin all screens (forums, moderation, etc.) are just blank -- no list of posts. In addition I have the synch message at the top, but it does not synch. After only a few seconds it says complete but the synch message comes back.
