12038	external scripts that interact with WPMU fail (redirect to sign-up page)	wpmuguru		"MU Trac Ticket: http://trac.mu.wordpress.org/ticket/1074



require('/home/httpd/htdocs/wordpress-mu/wp-blog-header.php'); in a script that interacts with WPMU fails as internally there is a redirect to the sign-up page, and therefore the php code below doesn't have a chance to run.

The reason is wpmu-settings.php line 119: $current_blog = $wpdb->get_row( $wpdb->prepare(""SELECT * FROM $wpdb->blogs WHERE domain = %s"", $domain) ); does not work as $domain is guessed from $_SERVERHTTP_HOST? but in my system that does not give useful info.

Adding the following line it works (it gets $current_blog from $current_site->domain instead):

if (!$current_blog) $current_blog = $wpdb->get_row( $wpdb->prepare(""SELECT * FROM $wpdb->blogs WHERE domain = %s"", $current_site->domain) );

A similar problem may happen at line 149 but I could not check it.
