FaceBook Login Error

Hello, I am working on setting up FaceBook authorization.

Here is the error:

URL Blocked: This redirect failed because the redirect URI is not whitelisted in the app’s Client OAuth Settings. Make sure Client and Web OAuth Login are on and add all your app domains as Valid OAuth Redirect URIs.

I am not sure if this is an error on my FaceBook App page or my plugin set-up.

Any help to get this set up would be appreciated.
