First, amusing topic and description. Second, sorry for the troubles.
I'm not actually seeing the error you mention at the top of that page (or anywhere on that page for that matter). When I go to it, I see a "Find local businesses" page with a category listing. On the left side, the Login With Facebook (what should be a button) is just text. Looking at the HTML on the page, it seems like the JFBCSystem plugin is not enabled. Can you check that and publish it?
If that's the cause of the problem, let us know. Otherwise, if there's something that we need to 'do' to make the error appear, let us know, and we'll do that to see what's up.
Finally, CB version shouldn't really matter. We've tested JFBC on 1.2-1.4. If you're on something prior to 1.2, let us know.
Thanks!
