In the page's HTML output, there's the following line in the body tag:
config='{"twitter":1,"plusone":1,"facebook":1}I believe your template is trying to load the Facebook Javascript library and that's causing a conflict with JFBConnect. Can you go through your template and see if you can disable any Facebook integration and test again?
Let us know if that doesn't help, but if you find the switch, please disable it so we can test further.
Thanks,
Alex
