After I swapped over my domains and updated every instance of the old domain in the database and everything else in this guide:
My main domain works, but none of the subdomains do any more. Dashboard or otherwise. Any advice?
Main domain here: http://maaa.org (my sub domains: eusa.maaa.org, neh.maaa.org)
I figured out the issue. Since we weren't managing the domain we had it pointed via an A record only and therefore couldn't just have subdomains on the fly. So I requested the person managing the domains to create these subdomains for me on their end.
