Domains not working

Hi there,

I’ve gotten this plugin to work (and it still works) on one multisite install but it’s been a couple of years. Now I’m trying to get it to work on another. Here are the details I hope you need:

The main site is working at https://endthewaronwildlife.org
Additional sites are working on subdomains: (just copies at this point):
https://bravenewwild.endthewaronwildlife.org
https://action.endthewaronwildlife.org

I added the two domains in the cPanel “Aliases” area, which is the same thing as where “parked domains” used to be I guess. A records point to the IP address for both.

I installed the plugin, moved sunrise.php and activated sunrise in the wp-config.php file.

I have domain options 1-4 active (although I tried just 2 and 3 as well)
I added the two site IDs and their domains to the Domains page.

When I go to the subdomains, they work. When I try typing the new domains that should be mapped, it goes to the signup URL (https://endthewaronwildlife.org/wp-signup.php?new=bravenewwild.org) although I have registration disabled.

If I then go to My Sites > Network Admin > Sites > Edit and edit one of the sites to use the domain (I did this with the bravenewwild.org and left it) the site loads BUT I can’t log in because it gives me the “ERROR: Cookies are blocked…” error. This happens with DM Options 1-4 checked AND with options 2-3 checked.

Please help – what am I missing?

Thank you,
Michelle
