Thread:Project:Support desk/problems loading css/reply (17)

Have you tried manually changing debug=false to debug=true in the load.php query string for the CSS? That's what tipped me off to the workaround that helped for me, and it's possible I wrote something incorrectly in my earlier post. Since then I have upgraded to a newer version of MW to no avail, and tried fishing with various .htaccess and php.ini settings.
