Can't configure the permission and tokes section in ultimate facebook section.

Hello,
During the configure process for ultimate facebook, I couldn't somehow figure out how to configure the permission and token section. The antenna signal keeps moving and once I click on reset auth tokens, the error message appears. " 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.

Best,

Austin
