Sorry for late response. But the issue seems to be Corrected now. It was an issue with my hosting provider and they had to fix whatever error it was.
I have the same problem. What is a httpd.conf?!
Problem Solved.
I thought I had created the Wild Card Subdomain *.boingblogs.com/ but I did not enter the root name Correctly. I had entered the root as public_html but it should have been public_html/boingblogs.com/
