Multisite problem

Hi,

I’ve installed a multisite with sub-domain mapping, wildcard is set and all is installed/edited as should.

I can create sites, but I cannot reach them.
The strange thing is that when I tried an installation multisite with sub-directories,it works.

But I need the sub-domain mapping.
It’s on a dedicated server.
Any idea what causes the problem?

Thank you.

Have a nice day.
