I just upgraded to 3.3, and have an issue with users logging out. When a user has logged out and then revisits a page that was already visited, the admin bar still shows at the top of the screen and the sidebar login still shows the user being logged in. Clicking on any links, though, will take the person to the wordpress login page, so the logout process is actually working. It just appears that the cache shows the same page whether the user is logged in or not.
I know this could be the result of settings or plugin conflicts, but have you seen this behavior before?
Thanks.
Jeff
