I can't create a domain in a reseller after installation.

hi i installed ubuntu 16.04 on my home desktop.

Then the apcu and php-apcu-bc packages.

Then it goes up to imscp 1.5.3 version: 2018120800

I enter the admin panel where I create the reseller then I switch over and there when I finish adding the domain on the last page of the domain addition.

He leaves with a mistake. To find the administrator error.
