The site in question has just been moved but we cannot get the subdomains of the site to work. The subdomains which are pointed to by a domain mapping plugin work but the subdomains of the site do not.
The site is on a VPS using a plesk control panel, the domain name is registered at Godaddy. All the settings look good to me but clearly they are not so need someone to check the settings and diagnose the problem and fix it.
Any questions please ask.
