WordPress MU

Hello,

I recently installed WPMU and I have noticed that it won't allow me to post to the main blog (www.perfectkaos.net) with the following error:

"As you are not using virtual hosts, it is not possible to post anything to this primary blog because the URLs of your posts could potentially conflict with weblogs living at this site. Please consider using virtual hosts as described here instead so that your website will have http://blogname.perfectkaos.net/ format addresses instead of http://perfectkaos.net/blogname/ format."

As far as I know, I have set this up correctly with virtual hosts.

Any idea whayt I could be doing wrong?

Okay, so investigating further into this, I spoke with my webhost over at Directoris.com- and he advised that he believes that Virtual Hosts are set up, as the Ensim control panel requires it as well.

Could Ensim be interfering in this? I can live without subdomains for every blog, but I want to be able to edit the main blog at the root domain. And it doesn't let me because it "may interfere with other blogs".

Any help?
