17090,Multisite 3.1.1 Upgrade Redirect Loop Network Admin & Plugins,theshadowfan,,"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;
}}}",defect (bug),closed,normal,,Upgrade/Install,3.1,normal,invalid,,
