If you aren't seeing the Connect this account? text and Facebook button, it means that JFBConnect thinks that Joomla user has already associated their account to Facebook. Can you check the JFBConnect -> Usermap area and see if the "Super User" Joomla account is listed there with a Facebook connection? If so, that's why it's not showing on the front end.
The "Connect Your Account" links will only show to user's that registered through Joomla and *do not* have mappings to any of the configured social networks within JFBConnect.
I hope that helps, but if not, let me know.
Thanks,
Alex
