I logged into my Facebook account and created the developer account and then created the app by the link in the admin panel of my Q2A site.
Copied the keys to the facebook configuration module and tried to login.
This message came after type my email and password:
A URL informada não é permitida pela configuração do aplicativo.: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains.
What I am doing wrong?
