I have networked version working properly with the subdomain setting. All is well on primary domain.
I setup a new subdomain but I wanted to change the URL.
Then I changed the settings in the network dashboard to http://www.newname.com (which I have registered and pointing at the root. The URL works! I can see the wordpress page but I can't seem to get to the admin console. The linking email wants me to go to the original name. The network dashboard points at the correct directory but my username and password are refused. Is there another database file I need to edit if I change the url?
