I am still having major issues getting my subdirectory sites to map.
I have followed all the instructions to the T in George Lerner's post.
The domain for the mapped site is pointing to the root of the main site.
However, when I enter the url for the mapped site, it redirects and to the goes to the url of the main site.
This is very frustrating especially since there doesn't seem to be any other solution to domain mapping out there.
