Wow, just went on a trip myself! Was reading a post in this sub-forum, clicked on the link (top of page) to go back to sub-forum and got bounced out to the permissions page. It also logged me out & wouldn't let me log back in! Stupid gremlins!
Some changes were made. Log out of the app then log back in. Hopefully it is now fixed. If having a issue using the browser clear your cache. Went in and out of the section and don't have to issue anymore. Report back of you still have a issue.
