FB Social loggin trouble

Hi

I am trying to get the plugin to work but am getting the below error when I attempt to use social login any ideas?

Warning
URL blocked: This redirect failed because the redirect URI is not white-listed in the app’s client OAuth settings. Make sure that the client and web OAuth logins are on and add all your app domains as valid OAuth redirect URIs.

The page I need help with: [log in to see the link]
