We're trying to upgrade from 2.9.2 WPMU (subdomain style) to 3.0.
The blog front ends show up, but we can't log in to the admin tools. There are no errors on the screen or in the error log- it just stalls out trying to get to any of the admin pages (you can access the login page, and entering a bad password will get you the expected error, but the correct password leaves you sitting there indefinately).
We've already tried...
manual install of core files
renaming our plugin folder
renaming our mu-plugin folder
removing all themes except twentyten
deleted wp-content/blogs.php & updated the .htaccess file
adding nonce salt to config file
other stuff in our config file, which may or may not be relevant:
define('WP_ALLOW_MULTISITE', true);
define( "WP_USE_MULTIPLE_DB", false );
define ('MULTISITE', 'true');
define('SUBDOMAIN_INSTALL', true);
//define('VHOST', 'yes'); // without this getting "Error establishing a database connection" unless multisite is defined as true
$base = '/';
define('DOMAIN_CURRENT_SITE', 'williams.edu' );
define('PATH_CURRENT_SITE', '/' );
define('SITE_ID_CURRENT_SITE', 1);
define('BLOGID_CURRENT_SITE', '1' );
define('FORCE_SSL_LOGIN', true);
Before adding the MULTISITE variable, we were getting database connection errors on the blog front ends if the VHOST variable wasn't defined.
Any insight would be appreciated. Thanks!
