JFBConnect Facebook Authentication Error

Autotune can't change all settings back to their defaults, so you'll need to make some changes above to get things back on track. Please set "Client OAuth Login" and "Web OAuth Login" to "Yes".

Then, go over to our Facebook Setup guide and follow step 14 to setup your "Valid OAuth Redirect URIs" in the same section. This portion was just made a requirement within Facebook; it used to be optional.

Thanks,

No problem. I'm glad we could help get you going. Should you need anything else, 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's certainly not required, but very appreciated:
