WordPress plugin that combines, minifies, and compresses CSS files.
You can debug the plugin by activating the debug option on the settings page and reviewing the server's error log for details. You can try excluding certain CSS files from getting combined to see if that fixes the issue.
= How do I use the "CSS Files to Ignore" feature in Settings?
You can tell the CSS Combine plugin to ignore certain CSS files by using the name of the actual CSS file (style.css) or providing the theme or plugin name followed by a colon and then the CSS file (fooplugin:style.css or footheme:style.css).
