Carl,
Clear your cache. Our Javascript file (/components/com_jfbconnect/includes/jfbconnect.js) changed quite a bit with this release, and on your page, the 'old' version is still being included in a compressed and minified form. Clearing the standard Joomla cache should do it, but the compressed file looks like it's from your template, which in some cases have their own method to re-generate the combined Javascript.
Hope that helps, but if I've just confused the heck out of you, let me know!
Thanks,
Alex
