Just a quick question, i don't know if this is because of pro-site plugin or the setup wp multi site. The problem is this:
Case 1. http://www.abc.com - resolves correctly to the main site.
Case 2. http://abc.com - resolves to http://www.abc.com/prosite/?action=new_blog
Case 3. http://anything.abc.com - resolves to /prosite too (if there isnt blog named anything)
Shouldn't Case 2 & 3 resolve back into the main site instead of /prosite?
In my DNS editor:
abc.com. 14400 IN A 123.345.66 http://www.abc.com. 14400 IN CNAME abc.com *.abc.com 14400 IN A 123.345.66
