The theme is broken when I enable the "Optimize CSS files" option The theme I made is broken, when I enable the "Optimize CSS files" option. I have cleared the cache, but the theme still doesn't work. With Firefox and Internet Explorer it is OK, but with Google Chrome is not OK at all.
How can I fix this?
I have that in all my CSS files, and it works fine in Chrome.

try: 


converting the CSS file to UTF-8 (if it's not)
removing any multiline comments
