I also got this error
Fatal error: Call to undefined function get_user_count() in G:\websites\server4.localhost\wordpress3_beta1\wp-admin\ms-admin.php on line 21
on SuperAdmin > admin
Almost every page of Superadmin area is showing some error.

I’m getting the same error using Dreamhost:
Fatal error: Call to undefined function get_dirsize() in /demo.andrejcarter.com/wp-admin/includes/ms.php on line 458
Same error on the same line for me. Followed the multi-sites instructions to a “t”. Fatal error: Call to undefined function get_dirsize() in /home/public_html/wordpress/wp-admin/includes/ms.php on line 458
Despite the fact the install says you can put the additional wp-config.php code anywhere in the file, you have to actually put it anywhere before the last two lines of code. Put your custom wp-config.php code before this:
/** Sets up WordPress vars and included files. */
require_once(ABSPATH . 'wp-settings.php');
I chose to put my code here at the bottom of my wp-config.php:
/** Enable Multisite features. */
define ('WP_ALLOW_MULTISITE', true ) ;
define( 'MULTISITE', true );
define( 'VHOST', 'no' );
$base = '/';
define( 'DOMAIN_CURRENT_SITE', 'mysite.com' );
define( 'PATH_CURRENT_SITE', '/' );
define( 'SITE_ID_CURRENT_SITE', 1 );
define( 'BLOG_ID_CURRENT_SITE', 1 );
/* That's all, stop editing! Happy blogging. */
/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
define('ABSPATH', dirname(__FILE__) . '/');
/** Sets up WordPress vars and included files. */
require_once(ABSPATH . 'wp-settings.php');
Took me a few tries to figure this out.
Awesome – thanks! Those pesky errors are gone.
