We discussed earlier, but I always like to keep forum posts up-to-date
The issue seemed to be a URL rewriting issue which was changing the JomSocial profile link, when logged in, to something really weird. It didn't seem JFBConnect related, because when on the 'right' profile page when logged in as just a Joomla user, if I clicked the Logout button, it would take me to another wonky URL.
Hope you figure it out, and definitely let us know what you find. Good luck!
