I have an MU site and would like to have multiple domains where sub site admins can still edit their own sites ( bc right now editing a site's url to a new parked domain doesn't allow admin access) . I've added the MU-domains plugin , following all extra instructions for the sunrise file and wp-config.
When new domains are added, I get the error "Couldn't resolve host .."
Everything for this in wp-config from define('WP_ALLOW_MULTISITE', true); matches perfectly except define('WP_DEBUG', false); shows just before it and there is no /**
Do I have to have a mapping plugin?
