define("WP_CONTENT_URL", "http://static.yourwebsite.com");

Hi
I am trying to set up a cookie free domain but i am having trouble.
I have set up a sub domain http://static.canonwindows.co.uk
and i am adding the following code to my wp-config

define(“WP_CONTENT_URL”, “http://static.canonwindows.co.uk”);
define(“COOKIE_DOMAIN”, “www.canonwindows.co.uk”);

but when I add the code to wp-config it causes problems with my css.

I suspect it may be because i am using cloudflare – has anyone had experience with this please?
