Thread:Project:Support desk/css broken on my wiki

Hi all

I've some problem on my wiki

MediaWiki 	1.18.1

PHP 	5.3.5 (apache2handler)

MySQL 	5.1.41-3ubuntu12.6

my pages are all without formattin... something like this: http://soppalco.ovunque-si.it/~mirko/owinkui/noType.png but if I use firebug to adding the type attribute to link tag I obtain something like this:

link rel="stylesheet" href="/cert/owinkui/load.php?debug=false&amp;lang=it&amp;modules=mediawiki.legacy.commonPrint%2Cshared%7Cskins.assoporti%2Cvector&amp;only=styles&amp;skin=assoporti&amp;*"

http://soppalco.ovunque-si.it/~mirko/owinkui/withType.png

Someone can help me?

thanks in advance
