If I go to

and log in using Facebook Connect, everything is fine.

However, if I go to

http://mydomain.com (ie, without the www) I get the following:

The Facebook Connect cross-domain receiver URL http://mydomain.com/xd_receiver.htm#...%220.168%22%7D must have the application's callback URL http://www.mydomain.com/xd_receiver.htm as a prefix. You can configure the callback URL in the application's settings.

ie - the mod works fine for 'www.mydomain.com' but if you access from 'mydomain.com' it doesn't work as the callback url is configured as 'www'mydomain.com'

I could only see one place in Facebook to enter the callback url, so how is this fixed?!

The facebook documentation does suggest that you use the domain without the www. on as your callback address. In effect the www is a subdomain and to spam multiple subdomains you have to supply the root domain only
