How to create subdomains in ISPManager?

Question

Domain Name System

I fell into the hands of an absolutely clean VDS with pre-installed ISPManager 5 Lite. (absolutely not configured - only script installation)
I created a www-domain for my site mysite.ru
after that I try to create a www-domain, which is a subdomain of mysite.ru, but I get an error

You do not have sufficient rights to access the domain name

The site has permission for autosubdomains in separate folders.
On DNS'e the mysite.ru domain is registered as master. A-record *.mysite.ru. is present.
At the same time, if you go into domain names and there you first create an entry like sub.mysite.ru - the www-domain is created normally

Answer 1

Jenny, it's not funny. There is a problem.

Answer 2

Make sure the correct user is selected when creating the subdomain
