In the setting of my App, I have set the site URL to be http://localhost/, in the app domain, I have indicated localhost.

Followed by in the Facebook Login Product, I have set Valid OAuth redirect URIs to be http://localhost.

but launch in my application, it gives me

URL Blocked .... redirect failed because the redirect URI is not whitelisted in the app's Client OAuth Settings...

the redirect URI link is http%3A%2F%2Fstaticxx.facebook.com%2Fconnect%2Fxd_arbiter%2Fr%2Fao6eUeuGXQq.js%3Fversion%3D4

No matter what I change in the OAuth, the URI remains the same.
