Before you ask - yes I have read all the other posts that seemed to match my problem. I've cleared cookies, internet files, closed browsers, restarted the computer, even downloaded Netscape Navigator but I still cannot get the "you are logged in as ..." page up. I can post messages and register users (although these also can't get the logout page either. the url for my site is http://www.abmus.org.uk/a&bforum1/default.asp . My ISP does not give me access to IIS bits so I cannot check the root folder.
I just registered (user test), and a cookie is being written, but doesn't seem to get recognized. I think, don't pin me down on it, that it has something to do with the URL containing the & sign.
