So, this panel demands much time and efforts to be installed. In 5 cases out of 10 I was unlucky. I managed to install it only under Debian. It appears, that the developers made all those difficulties on purpose: to order the only paid service on their site: panel installation on your host. The rest is OK. The panel is very convenient, fulfills the task well. But! The panel is highly specialised. To alter in it something means to go mad. It is very standard and can be used only for resellers creation, user profiles creating, editing of domains, etc. Forget about any hand-held editing of configs. The client interface is not less convenient and standard than the admin. panel: the same beautiful buttons, but of no use.
