TypeError: jfbc.init is not a function

Please make sure you clear your Joomla and possibly even browser cache after the update. The jfbconnect.js file was updated extensively in this release, and if the new copy isn't being loaded, that would be the likely error I'd expect.

If that doesn't appear to be the problem, let me know the page where I can test on and we'll gladly dig in deeper.

Thanks,
Alex
