When users go to do things on the site (2.5.6) in areas for which they have full permission in groups and module levels, they are reporting that when they go to do things like register, or proceed to the detailed page of register, open a forum, post a message, they get the

"Sorry you do not have permission to access this area status banner"

even though they have all permissions, and the system does give them access the page they are trying to access.

Doesn't make sense. Anyone have any idea why this banner is harassing users?
