JFBConnect suddenly broke

Everything in your app picture seems correct. When are you getting that error? I'd recommend using the Autotune configuration tool, which has checks built in for automatically setting values appropriate for your app and that will work with JFBConnect.

You would need an active subscription to fetch the latest settings and recommendations for Autotune though. Additionally, depending on how old of a version of JFBConnect, the Autotune configuration tool may need to be updated due to (constant) changes that are made within Facebook.

The latest version of JFBConnect is v5.2.2 and support Facebook, Google+ and Twitter authentication, along with a lot of new features.

I hope that helps give you some ideas on how to proceed. We don't use the FB Developer App area very much anymore as it's constantly changing and, honestly, sometimes buggy due to those changes. Because of that, I can't give you a straight answer to what may be wrong, especially since things look right from your pic.

Thanks,
Alex

We don't have any discounts currently running. Unfortunately, the only constant with social network integration is change. Facebook (and Google and Twitter) are always changing their interfaces slightly, which means the longer you are out of date with a new release of JFBConnect, the more possible it is that something may break.

With that said though, I just re-read the error you were getting and looked the code of your site. The conflict is actually being caused by your mod_js_facebook_popup module. It's re-including the Facebook javascript library and doing so in a way that conflicts with authentication in JFBConnect.

You'll need to disable or fix that module.

I hope that helps get you going,
Alex

No problem, we're glad to help. Obviously, we'd recommend upgrading JFBConnect when you get a chance. In addition to new features, you'll be assured that all compatibility updates for changes with Facebook will be implemented as well.

Either way though, v5.0 of JFBConnect should be functional for quite some time. If you do need anything else, or have any feedback or suggestions for future improvements, just let us know.

Finally, if you haven't already, please consider leaving a rating and review for JFBConnect, or our support, on the Joomla Extension Directory. It certainly isn't required, but is very appreciated:
