Facebook not recognizing subdomain

Hello,

Facebook is not reconizing subdomain yf as a subdomain.

Given URL is not allowed by the Application configuration: 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.

I have screenshots of it working and with widgets in the footer. Footer widgets dont work anymore either. Maybe because I enabled a couple widgets at other primary?

Thanks
