domain mapping: server not found for the domain added but other pages work


I tried installing the domain mapping plugin for my sub directory site and got the dedicated ip for my hosting account. The first time I probably did something wrong and screwed up my database so I asked my hosting provider to wipe everything and I started from the beginning again.

2nd attempt

I carefully read the instruction and followed through. The result is that when I type in the domain name. Firefox says “Server not found. Firefox can’t find the server at”

But when I try to view a post, for example, it does work!

Please help.

Thank you,
