deleting .sass-cache folder

[Path Finder LifeRay, geändert vor 12 Jahren.]

Hi all,
When I create a 6.1 theme it is creating .sass-cache folder in css and after deploying the theme I am getting the following error.

[DynamicCSSFilter:181] Unable to parse SASS on CSS E:/tomcat-7.0.25/webapps/ROOT/we
b/guest/css/main.css
org.jruby.embed.EvalFailedException: (SyntaxError) Invalid CSS after "": expected selector or at-rule, was ""

how to remove this? any suggestion is great

Thanks & Regards,
Path finder
