No subdomains

[Sens0r]

Hello,

I write this post, because I have a problem with my ispCP installation.
I use this on a server running a confixx installation lastly, so it might be possible that the problem is related to this fact, I don't know.

The first of my problem was that I had to login to ispCP, after the installation, through the main domain of my server, and not through admin.myserver.com
Then I found out that none of the subdomains works, so I started searching why this isn't working, read a lot of documentation but wasn't able to figure out what might cause the problem.

So, do you have any hint how I can fix this? I'm grateful for every answer.

Thanks,
Steven
