FB login giving URL Blocked error.

I am using WordPress Social Login for FB, it was working fine but last night I change something on FB and getting the following 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.

Please check and help with what I am missing or doing wrong.
