Failed To Login!

When I click the social login, it fails to login. Goes throughthe loading page and everthing, then once it reaches this page https://www.avilamassagespa.com/login/?action=wordpress_social_authenticate&provider=Facebook&redirect_to_provider=true#_=_ it turns white and stops.

Any ideas?
