我使用了MU域映射插件来映射域，目前，我无法登录到指向其他域的其他子网站。

它向我显示了错误。

The domain mapping plugin only works if the site is installed in /. This is a limitation of how virtual servers work and is very difficult to work around.

define(\'WP_ALLOW_MULTISITE\', true);
define(\'MULTISITE\', true);
define(\'SUBDOMAIN_INSTALL\', false);
define(\'DOMAIN_CURRENT_SITE\', \'mydomainname\');
define(\'PATH_CURRENT_SITE\', \'/\');
define(\'SITE_ID_CURRENT_SITE\', 1);
define(\'BLOG_ID_CURRENT_SITE\', 1);

define( \'SUNRISE\', \'on\' ); 

define(\'ADMIN_COOKIE_PATH\', \'\');
//define(\'COOKIE_DOMAIN\', \'\');
define(\'COOKIEPATH\', \'\');
define(\'SITECOOKIEPATH\', \'\');
