I'm having trouble with Facebook connect.

In Safari, Chrome, and IE I get this when people try to login with their Facebook.

API Error Code: 191 API Error Description: The specified URL is not owned by the application Error Message: redirect_uri is not owned by the application.

In Firefox it works perfectly and their name and profile pic shows up as if they were logged in.

These are my Facebook app settings and I'm not trying to redirect to another site. The entire page url is like this:
http://www.mydomain.com/BestOf/

Site URL
http://www.mydomain.com/

Canvas URL
http://www.mydomain.com/

Any ideas?
