i don't know what happened here. I created a site and worked on it without mapping the domain. then when I tried mapping the domain it kept going to the main site's registration page.
The only way to get the domain to route is to input it in the Network Admin>Sites>mysite>Domain and change that from something.networkdomain.com to something.com. But then when I try to access the admin which is on something.networkdomain.com/wp-admin, it takes me back to the main site's registration page.
