Thread:Project:Support desk/MediaWiki not displaying properly on Internet Explorer

Hi guys. This is my first attempt at setting up a Wiki using Ubuntu server. I've gone through the initial setup, and everything seems to be fine except the Wiki does not display well with Internet Explorer at all.

It looks fine in Firefox, Chrome and Safari. I don't see any errors in the PHP logs and I'm not really sure where to go from here... I've attached images to demonstrate.

Firefox Internet Explorer

Thanks for any help in advance...
