mortydot on "[Plugin: W3 Total Cache] CSS and JS files empty"

Hi,

I'm using a multisite environment and testing with this plugin. I noticed that the css and js header links are created for minification, but when folowing they return empty (blanc page).

A other multisite works, there the files do generate.

This is the debug info in footer of the page:
