I have had multisite for around two years. Never had any problems until I downloaded WPMU DEV Dashboard.
From what I can tell when you activate that plugin it also activates domain mapping. So I had two domain mapping plugins.
I deactivated them one at time and tried adding a domain and nothing worked.
I deleted one and still nothing.
When I add my domain that is added.
When I add a site and look at my list ALL of the domains show the correct mapping BUT the one I just added. It doesn't say anything in that field.
Now what's odd is I can delete the domain and try the site and it comes up. But if I leave the domain it reverts to the primary domain.
So that being said my problem is it doesn't go to it's own domain and reverts to the primary domain no matter what I do.
The primary domain is http://www.lagunabeach1.com.
The subdomain is http://www.collincountyevictions.com.
I have about 100 websites and as I said have never had a problem adding sites. I am sure I am missing something very small here and can't wrap my brain around it.
Any help appreciated. Thanks
