We have a major issue with visitors logging in and not being allowed to upload a video. It seems that they are shown the signup page when, of course, they have already signed up AND they are logged in!

It is made even stranger because on some pages the username will show at the top with the private messages, and then click onto another page and it disappears - showing the generic Log In and Sign Up and Help links.

Has anyone else experienced this - if so what can it be.. please help!
