Mediawiki -> subdomain

For some reason, I can’t figure out how to do this…

My domain has a vBulletin installation in its root. It also has a MediaWiki installation in a subdirectory called ‘wiki’. Therefore, I can access my wiki through However, I’d prefer to use to access it. But when I put that into the browser, it tries to go into, which doesn’t exist.

I’ve looked at DH’s wiki and its information on subdomains and mediawiki installations, but I just can’t figure out how to do this. There was something in the DH wiki about subdomains and MediaWiki installations, but it also said something about how it will make all files on that domain (which would include my forum I guess) to run through MediaWiki, which I don’t want…

I am so confused.

When you created the subdomain for your wiki, did you leave it at the default setting

Or did you check the option that says

For your purposes this would be the option you need, I think.
