I frequently get this error message:
Recently an error occurred while creating the CSS / JS minify cache: Unable to cache remote file: "http://www.skolappar.nu/?pageless=1"
What am I doing wrong? I've only enabled "combine".
I've asked the developers of the theme I'm using and they say: "The PageLines compiled CSS file isn't a file and is generated. This means that W3 Total Cache can not minify it".
