i know why…
when i added sample1.eu.org it become error but success to create website and can add manual new DNS Zone with empty value
from phpmyadmin i only can see only eu.org
then i try to add
eu.org…i check add/delete dns…success with full zone
then i add domain samplesub1.eu.org
i can see the zone for samplesub1 inside zone eu.org
but if i create website samplesub2.eu.org it failed again (same error) but success to create website and can add manual new DNS Zone with empty value
and it happen too when i convert the subdomain to website
now the question:
is cyberpanel not allowed host website(add website) using “outside” subdomain ?
