Facebook Given URL is not whitelisted in Client OAuth Settings

Those redirect URIs look correct to me.

* Could you try temporarily removing any IP whitelist settings that you have and see if there's any effect? Once we get the login via Facebook working, you can also re-set those up.
* Please review our Facebook application setup guide to make sure you've followed our steps for setting up the application.
* I'd also suggest running Autotune in our JFBConnect backend to compare your settings to our recommended values to see if there are any other issues as well.

This should hopefully help you move forward, but please let us know if you continue to have issues.

Ahh, looking at your site and the screenshots again, you're missing the subfolder from the redirect URI's:instead of
Alex also just tested the login and it appears to be working, so let us know if you continue to have problems.

Yes, in the redirect URI settings in the Facebook App. (Settings > Advanced > Valid OAuth redirect URIs)

The authorized URLs would probably not be the problem in that case. My guess is that it's the Site URL setting. In your app on Facebook, go to Settings > Basic tab. Make sure that the following are for the staging site and not the live site: Site URL, secure canvas URL, and secure page tab URL. Also make sure that the App Domain would work for the staging as well. Let me know if this helps and when you're ready for live, you can change them back for the live site.
