I followed the <a href="https://help.ubuntu.com/community/MediaWiki">instructions in the Ubuntu Community Documentation</a> for installing MediaWiki, I've gotten up to the point where you're supposed to browse to ://wikiserver/mediawiki, my problem is that when I do this with any web browser, I'm prompted to download something rather than have it display the webpage.

My googlemancy hasn't been up to the task, any advice would be greatly appreciated.
