I've applied all the fixes that I know of and I'm using the nightly build from 12/8 yet I can't get my new blogs work. The I go through the process of creating new blogs but when I finish, the newly created subdomains do not work.
The blog that I created is at http://dwblogs.com/ and the subdomain is at http://agape3.dwblogs.com (which doesn't work). I've even had the server support staff apply the suggested fixes. Yet the new blogs are working. HELP!!!
