Knownhost VPS & domain mapping not working

WP 3.3.1, Domain Mapping 3.0.7, Multisite, Subdomain, Wildcard domain setup

Followed directions exactly, this is a migration of a site from Hostgator and everything else is working fine, then I change my A records with my registrar, give it 48 hours to propagate and all I get is a blank screen.

Knownhost said to contact the plugin developer, so now I'm back here. Any suggestions/tricks?
