Wittydan,
If you just upgraded to JFBConnect 4.1, you may need to clear your browser cache for it to work. Everything else on your site looks right to me, and when I try to login, the proper authentication box comes up.
Richard,
Not sure what's wrong with your site. What version of JFBConnect are you running? We don't have any subscription to JFBConnect on file for you. Priority support is for subscribers only, so we likely can't help you, especially if you're not running the latest version.
Thanks,
Alex
