 I have Wordpress MultiSite and was upgrading from 3.1 to 3.1.1. Both my
 Network Admin and my website displayed redirecting loop errors. The
 website was initally caused by the Plugins, so I disabled those and the
 redirect loop error was removed. However the Network Admin error remained.
 My server provider found code in the admin.php that was causing the issue:

 We had modifed the following code from the file "admin.php" in the path
 "/wp-admin/network".

 ===========
 Previous Code

 if ( ( $current_blog->domain != $current_site->domain ) || (
 $current_blog->path != $current_site->path ) ) {
 wp_redirect( network_admin_url() );
 exit;

 ===========
 Corrected Code

 if ( ! is_main_site() ) {
 wp_redirect( network_admin_url() );
 exit;
