WP 3.2.1 multi-site admin is working fine.
I've created a wildcard subdomain as required.
I've also created a subsite as part of the multi-site network, and set it's subdomain to be photo.example.com
However, this URL loads a blank page. If I try http://www.photo.example.com, I get my ISP error page, so without the www. prefix must be working DNS-wise, otherwise I'd receive an ISP error page for that too.
In /wp-admin/network/site-info.php?id=3, Path is set to /
Is this correct?
URL is set to photo.example.com. Attributes is set to Public.
