Title: Update fb login feature{Issue:FB OAuth2(callback:=>invalid_credentials)}

Add the omniauth failure inspector. The error of "invalid_credentials" is actually depending on OAuth callback operation between the "Cross-Site Request Forgery" validation feature on FB OAuth provider and OAuth's operation of omniauth-facebook library. Can you repair it?
