I want to change xenforo's css serving extension. I already did change statical ones but I couldn't figured out how to change dynamical ones which works with this code ; "<!--XenForo_Require:CSS-->"
For example this one ;
<link rel="stylesheet" href="css.php?css=action_filter
had to be like this ;
<link rel="stylesheet" href="css.js?css=action_filter
I want to change only the extension.
