[Mediawiki-l] Short URLs with PHP as CGI, CSS mangled

[Azurite]

I checked on the link just on a whim today, and rather than showing me a 
CSS-less version of my Main Page, it seems to be redirecting infinitely 
into the wrong directory. Based on the code snippets from my 
LocalSettings.php and my .htaccess (from the public_html folder), what 
is causing this? My wiki isn't hosted in a folder called "wiki," but 
that seems to be what it's looking for, for some reason. Where should I 
edit?
