3 minute wait time as of right nowThank you for the offer Nic and Kenneth. The problem with opening a ticket is that it may take a while before being looked at, whereas in reality one typically wants to unpark a domain now.
I want to make a suggestion: Seeing that List Parked Domains is compiled from httpd.conf (or so it seems), would it not be a nice idea if the unpark script would fall back on the httpd.conf information if WHM is unable to determine the user otherwise?
