MyBB Community Forums

The thing is, my forums are currently at paparanho.com, but as I'm about to upload Wordpress to the root, I want my forums to be accessed with forum.paparanho.com. So my cookie settings should be:
Cookie Domain: .paparanho.com
Cookie Path: /forum/

Right?

So then, after setting up my urls in the general configuration menu, I have to move my forums to a /forum/ directory right? Is that all?

If the domain would be forum.paparanho.com then your cookie domain needs to be .forum.paparanho.com and the cookie path needs to be /

Then you can move the forums yeah... remember that if you want to sue forum.paparanho.com you'll need to setup the subdomain in our host's control panel, moving the files to /forums/ won't automatically make forum.paparanho.com point to the forums.

How do I make forum.paparanho.com same as forum.paparanho.com/index.php.
In http://forum.paparanho.com/ it only says "This is a placeholder for the subdomain forum.paparanho.com"

EDIT: Got it to work, there was an index.html file, I deleted it and it now works as I want. Thanks.
