I agree. I don't what else to try. Logging out and back in did nothing. Oh well, it's not affecting anything. I'll chalk it up to a 'glitch'. Thanks for the suggestions.
My 'Notifications' box at the top right of the page indicates '2 unread private messages' but when I click 'Private Messages' there is nothing in my inbox. In fact all my message folders are empty. If I select 'empty folder' nothing changes. What am I missing?
