Thread:Project:Support desk/css not displayed / issue with wgStylePath perhaps?

I have tried frustratingly to setup a new Mediawiki site on a local intranet (no links, sorry). Everytime (I have installed via two seperate tarballs and synaptic package manager) the MediaWiki installation script goes smooth, tables are created, I move the LocalSettings file and the home page is displayed (http://mydomain.com/mediawiki/index.php/Main_Page). But CSS is never displayed! I have played with the wgStylePath, wgServer, etc etc to no avail. What is strange is that firebug will even display the contents of the css files (from the html tab, but not the css tab).

I am thinking it has something to do with the /Main_Page on the end of the url killing the relative path because the css and javascript are accessible via browser (manual address entry), and the fact that this is an existing server that may have some apache or php configuration setting that is adding the slash instead of some other character? or is there something else I am missing? Any suggestions or thoughts would be a great help, sorry I can't provide configuration files. Thanks in advance!

The Environment: PHP 5.3.5 MySQL 5.1.54 Apache 2.2.17 Ubuntu 11.04 Tried MediaWiki v 1.16.4 (tarball), 1.16.3 (tarball), 1.15.3 (Ubuntu Repo)
