Wordpress Chat Not Working when Facebook API is setup

The site has a bunch of errors in admin and frontend when chat is enabled with the facebook API

Warning: file_get_contents(https://graph.facebook.com/me?access_token=
) [function.file-get-contents]: failed to open stream: No such file or directory in /home/............. on line 1605

I had to move the chat to another server since sitground was turning off my site due to overload. The new site is http://chat.vyzionradio.com

Does chat work with a subdomain ?
