I have installed ISPConfig 18.104.22.168 on OpenSuse 11.1 and I have this problem.
Like admin I create Reseller, then I login like new Reseller and create new site. But the new site is under folder /srv/www/clients/client0, but the new Reseller is client1, when I change it under admin than all is ok.
When I create the second Reseller, then I login like second Reseller and create new site, and the folder is /srv/www/clients/client1, but the second Reseller is client2. Under the admin I see that the owner of site is client1 not client2.
It's like problem with counting Resellers.
I try install the new server with ISPConfig, but it's the same problem.
And sorry for my English.
