Another WordPress installation on a subdomain of a network

Hello,

At the moment, I’ve the following setup:
– A WordPress network at *.blogs.mysite.com where all my network blogs

I want to create a clone of this, at dev.blogs.mysite.com, with a *.dev.blogs.mysite.com as the subdomain, with a separate database.

I’ve configured my dns zone, apache virtual hosts, etc etc, but when I enter in dev.blogs.mysite.com I get this error message: “No site defined on this host. If you are the owner of this site, please check Debugging a WordPress Network for help.”, even though I’ve disabled the network in wp-config.php from dev.

Is there any way to resolve this problem? Or it is impossible to have another wordpress running under a subdomains’ network?

Thanks!
