If the paths to your themes JS/CSS files are dynamic, they will automatically load from the CDN when the CDN is enabled. If the paths are static, they will not.

To load your themes JS/CSS files from the CDN, either edit your static links to full paths that include the CDN URL (including http://) or change them from static to dynamic .

To change your CSS/JS links from static to dynamic change them to look like this.

<link rel="stylesheet" media="screen" type="text/css" href="<?php echo CDN_URL; ?>/static-path/style.css" />

<script type="text/javascript" src="<?php echo CDN_URL; ?>/static-path/jquery.js"></script>

Standard concrete5 dynamic paths are supported as well.
