What I've done is the following:
Added these lines to my config.php:
and entered: http://cdn.forumediainc.com/rcf/xenforo/styles/default/ and saved it.
After that I tried force refreshing the page and the images are still loading from their regular spot rather than from the CDN.
For example, the node-sprite.png shows as being loaded from:
rather than loading from:
Both URLs work fine, but the non-CDN one is being used.
Could anyone point me in the direction of what I am doing wrong?
