Why do I now get a blank page after mapping a domain?

I had domain mapping working well – so easy to set up.

Now I get a blank page – no html, nothing – when going to that domain.

There’s two things that have happened which may have caused this error.

1) Upgraded to WP3.5

2) Upgraded to a new (dedicated) server.

I suspect it’s the server change, but although I have changed the A record and waited for the DNS to propagate, I now just get the blank page when entering those domains.

Is there something I need to do on the new server?

Any help very much appreciated.
