v4.0.1 of JFBConnect is almost a year old now, and very out of date. We'd highly recommend upgrading from that version to take advantage of Open Graph Actions, Facebook Invitations, and tons of new features. Additionally, there have been many bug-fixes both in JFBConnect and compatibility updates to ensure functionality works with recent changes in Facebook's API.
I'm not sure why the domain isn't showing, but with that old of a version, it could be for many reasons. If you need our help, you'll also need a subscription to JFBConnect, which you don't appear to have. To get one, use the page below to subscribe now. That will get you access to the newest release as well as priority support for any questions, like above, you may have:
