Thread:Project:Support desk/CSS is not loading properly/reply (9)

I had this problem too. I am using Apache rewrite rules to make very short URLs.

RewriteEngine On RewriteRule ^(images/|skins/|(api|img_auth|index|redirect)\.php) - [L] RewriteRule ^/*$ /index.php?title=Main_Page [L,QSA] RewriteRule ^(.+)$ /index.php?title=$1 [L,QSA]

After upgrading, there are more top-level PHP scripts that are part of MediaWiki, including load.php, which is a new script used to obtain skin CSS and images.

I added all the new top-level PHP scripts to my rewrite rule and restarted Apache.

RewriteEngine On RewriteRule ^(images/|skins/|(api|img_auth|index|load|opensearch_desc|redirect|thumb|trackback)\.php) - [L] RewriteRule ^/*$ /index.php?title=Main_Page [L,QSA] RewriteRule ^(.+)$ /index.php?title=$1 [L,QSA]

This fixed my problem.
