When I first looked yesterday, it was giving a generic WordPress "Oops, couldn't connect to the database" error page, and now it's giving a forlorn "Sorry, no posts matched your criteria.", along with an error message.
*later*
Hrm...Confusingly, if you click on one of the links in the "Previously on iBlog" section, the entries are still there, so it could just be WordPress or the database server playing up.
Cheers,
