Facebook login button error
 

I followed the instructions how to set facebook sign on button but returns this 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 "

Re: Facebook login button error
 

Ah, yes, the Facebook setting up is really not easy... You have to whitelist your URLs on the Facebook App side. Just try to find the OAuth settings and specify your URLs there.
