Well I was wondering about that, because this has happened before and has just happened again.....I just got home from a wedding...been away from the site for about 9 hours and went to this site....and am still logged in....
Checked around the site for a bit and again tried to log out and nothing.....all the other buttons on the site work for me but when I put my cursor over the log out button, the button highlights but nothing happens when I click on it.
