Another problem add subdomain

[dnikola]

Hello,
I have installed ISPConfid and evrything is working OK, but I can not add subdomains.
I try evrything but with no result.
Is there any step by step manual for this?
I read this pdf that comes with a ISP config but I did not find anything that can help me.

Please help.
I loose all day on this.
Thanks
Nikola

You must add subdomains on the Co-Domains tab.

Ok that is not a probelm, but where is index file for subdomain?
I have domain:
www.domain.com and I add co-domain test.domain.com.

I do not need forward to folder or domain, I need index file to be in
test.domain.com

[till]

The co-domain points to the same folder as the main domian, so they share the same index file.

If the subdomain shall have its own index file and folder, create a nwe website.
