I've run into a problem where no minified files (CSS and JS) are listed for upload to my CDN when clicking "Upload minify files" within the CDN section of W3 Total Cache. The option is enabled however.
Consequently when I configure W3 Total Cache to serve CSS and JS from my CDN my site is unstyled (404 errors on those resources).
Images and all other types of resources are identified correctly and can be copied to the CDN. Those resources are also correctly served off the CDN.
CSS and JS files are being correctly concatenated and served locally. I'm using manual minification and specifying the full list of files to minify.
I'm using memcached for caching (running multiple web servers), using version 3.2.1 of WordPress and version 0.9.2.4 of W3 Total Cache. My CDN is rackspace cloud files.
