pageOK message when using domain mapping

Followed all the directions, all that shows up when you try to go to that site is a white page with the word"pageok"

That happens either from clicking on a link to the site from the main site, or trying to get in with the domain name on the URL line.

Obviously it makes for a pretty boring site. Remove the Domain mapping and the site comes up normally, trying to get to the domain still brings up the white page. The full source of that page (with the tags removed) is:
