We're looking into what the issue may be. If you haven't already, please make sure you have cleared your Joomla caches. Also, please try closing your browser and re-opening it to clear it's caches as well.

It looks like this is a widespread issue with Joomla 3.1.4 affecting hundreds of extensions, including JFBConnect. It's likely that Joomla 3.1.5 will be released to fix the problem, but that's being discussed.

We're looking into releasing an updated version later today if 3.1.5 doesn't look likely to materialize.

Sorry for the troubles, and we'll keep you posted on if, and when, an update from us (or Joomla.org) should be available.

Thanks,
Alex

Just wanted to let you know that we released JFBConnect v5.0.2 for Joomla 3.x which resolves this issue.

If you have any feedback or issues, definitely let us know.

Thanks,
Alex
