Thread:Project:Support desk/Word files not uploaded

I recently created a wiki using the simplescript application on hostmonster. Here's the content of the Special:Version page

MediaWiki	1.17.0 PHP	5.2.17 (cgi-fcgi) MySQL	5.1.58-community-log

and here's the URL http://www.midnightswan.com/home/index.php?title=Main_Page

I've only been working on this particular site for a day or so, but I've come across an error I've never met, and can't seem to overcome. Whenever I upload a word document, I get this message:

Files of the MIME type "application/msword" are not allowed to be uploaded.

I don't know exactly what went wrong, I'm assuming something with the $wgMimeTypeBlacklist (though I never used this in LocalSettings.php). The wiki works fine for pdf files. How can I allow my wiki to allow word files to be uploaded?
