Using WP3 on new install.
I have similar issue. BlueHost doesn't support wildcard DNS. I created Subdomain in cpanel easily enough and it is live, but I can't get it to show in SuperAdmin panel in WP3. If I can't manage from WP what is the point? I looked in DNS zone editor and this line was created:
http://www.baltimore.goessolar.org. A 126.96.36.199
So why does WP3 not allow me to see it?
I went thru set up of WPMU activation but did not realize wildcard DNS issue. Modified .htaccess and wp-config.php as instructed.
Does all the subdomains need to be created before you activate WP MU features? If so that is a no go and I'll have to find a different host.
I don't need users to create sites on fly, so manually creating subdomains as needed is not a problem.
When I click create new site in SuperAdmin only option is subdirectory. I set Domains not subdirectory option when set up MU.
So if there is a way to get this working at BlueHost sure would like step by step advice. Maybe I have to delete everything and start over. Instuctions warn that can't change afterwards. There is not access to that screen anymore.
Thanks in advance.
