OK... here's what I want you guys to do. I want you to reset your cookie.
To do that is easy. Let the site do it for you.
Log out completely. Use the Log out button. (Top right hand corner)
Log back in with your user name and password.
Check the "New Post" immediately. If you see there are new posts then your cookie is stuck. If you don't show new posts then your cookie has refreshed.
To fix a bad cookie you must delete it. Problem is you will need to search to find it. If you delete all of your cookies using your browser you will lose all other site log in's you have stored.
