I can not create a domain in AdminPanel "Add Domain". There is the message "You need to have at least one user account!".
OK, i create an user account. There i must fill a domain name. OK, i create a user account with mydomainname.de.
In AdminPanel at "Domains" i can not create the same domain name as in the user account, because the domain already exist: ERROR! Domain mydomainname.de already exists on the server!
In the UserPanel of this new created user account are no domains. If i create mydomainname.de it throws the error "domain already exist".
How can i create a domain and use it as website?
