Error after upgrading from 5.0.2 to 5.1.1

Gui,
The issue is that the our Javascript file on your site has been cached in their browsers. We attempt to do some 'cache busting' to prevent that issue, but depending on how your server is configured, it may not work.

If you're using the System - Cache plugin or any other 'optimization' add-ons for Joomla or Content Delivery Networks, like Amazon CloudFront or CloudFlare, please purge the cache for /components/com_jfbconnect/includes/jfbconnect.js

The problem should generally clear itself up within 24 hours otherwise.

I hope that helps explain,
Alex

Awesome! I like solutions that we nail on the first try Glad that got you going. As always though, if you run into anything else, just let me 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:

Thanks,
Alex
