Import virtual server

I just upgraded to Vurtualmin Pro, and will use it on a ready configured Apache ubuntu server with Postfix etc.

So I dont want to vreate a new virtual server. But it seems that I don’t manage to import the ready configurations. I fill in the fields and press save. No errors reported.

But I dont get all the nice futures as creating new mailboxes, creating websited etc. as included as packages in Virtualmin Pro.

What is going wrong and where can I read more about this. I surfed arround the Docs. and did not find a good tutorial for a newbie.

So I need help to get started (not nowing manual programing of a server I bought virtualmin)
