I am trying to log out of Facebook, as usual, and when I click on the account drop down menu, I get a twirling grey circle and this: "The content you requested cannot be displayed at the moment. It may be temporarily unavailable, the link you clicked on may have expired or you may not have permission to view this page." This is happening on 3 browsers: Chrome, Firefox and Safari, so it is not a browser issue. How can I bypass this? Other FB navigation is working; just the account menu seems to be broken.
