[Plugin: WP CSS] Clearing Cache means empty stylesheet served

Hi,

I edited my stylesheet so I cleared the cache and all of a sudden wp_css serves an empty stylesheet because it can’t find my style.css file. here’s the content of my wp_css generated file:

File:/home/glasssli/public_html/glass-slipper-net/wp-content/plugins/wp-css/wp-css-compress.php<br />File not found: style.css

… but style.css is DEFINITELY in my themes folder because I added
<link rel="stylesheet" href="<?php bloginfo('template_directory'); ?>/style.css" type="text/css" media="screen" />

to get the stylesheet to show up and that works fine. What’s up?
