Big problem here, hopefully easy fix and greatly appreciate help. Right now I can see all my current sites but new sites are not being seen in the site admin, when I'm in the network admin. When I go into the network admin I can select the theme and go to 'administration' and it works. I can login to the site admin and view the sample post. I have noticed that sites are getting entered into the "wp_blogs" table but aren't appearing.
There must be one thing not set properly in the database. There is an error I discovered when upgrading some WP 2.9 MU sites. If you know what might be missing, please suggest and we'll see if it fixes the problem. Otherwise, I will describe what I had to do to fix the above problem by changing the wp_1_ prefix to wp_ (which should help others with this problem.)
(1) Database changes: My database had a split wp_table. The wp_options was actually wp_1_options along with a few other tables while wp_site was not in the "1" category. I had to change the prefixes to move the wp_1_tables to wp_tables to get it to work. Some tables are below.
(2) WP Config problems - did not work with "MULTISITE" true and only worked with ALLOW_WP_MULTISITE set at true. Adding with both resulted in a 500 error. Here is what my config includes - have no idea what it should look like officially:
define( 'SUBDOMAIN_INSTALL', false );
$base = '/';
define('DOMAIN_CURRENT_SITE', 'www.mysite.com' );
define('PATH_CURRENT_SITE', '/' );
