Not able to unpark a domain from WHM ?

Issue : A domain created as parked from cPanel can be deleted from cPanel, but fails to be unparked from WHM, with the following error message shown :

“The system cannot determine the base domain site cpanel”

Reason : On checking, we can see that the parked domain does not have any entry in DNS records nor in httpd config

Solution : # /scripts/upcp –force , it would update and fix any issue at cpanel for which DNS is found missing for park domains
