I recently mapped my primary site to a new domain. However, upon doing so, the network admin became inaccessible. I get a redirect loop when trying to access. I have seen a similar issue described here – https://premium.wpmudev.org/forums/topic/wp-multisite-login-loop-to-network-admin-main-site-links-redirect-all-to-homepage – but, unfortunately, setting up the site from scratch isn't really an option for us at this point. Any ideas for how we might resolve?
FWIW, I have already commented out these fields from wp-config.php:
// define('PATH_CURRENT_SITE', '/'); // define('SITE_ID_CURRENT_SITE', 1); // define('BLOG_ID_CURRENT_SITE', 1); // define( 'DOMAIN_CURRENT_SITE', 'domain.com' );
