Why are all subdomain blogs given a site id = 1, regardless of which top level domain wordpress mu website it was set up from (using wp-signup.php)
When created, the subdomain blog is showing the URL as hanging off the correct domain, but i have to go in and manually edit that new blog in phpMyAdmin to change the site id to match the top level domains site id. Otherwise you can't log in etc.
I'm running Wordpress MU 1.3.3 on a VPS (cPanel, Apache setting up parked domains etc), MySQL 4.1.22 (standard)
This may be an intentional feature, but I'm not so sure...
