Hi everyone,
I've got an issue that I'm not entirely sure on how I can solve, if at all.
Currently I have a site on www.<DomainName>.com, which was previously a multisite with a couple of <subdomain>.<DomainName>.com underneath.
Multisite on DomainName.com has been disabled, and a new multisite/installation on <subdomain>.<DomainName>.com has been created and is in a FTP folder called Subsites, where it redirects to when using <subdomain>.<DomainName>.com – There is no wildcard, because it's ad hoc for certain domains, as they are created.
The <subdomain>.<DomainName>.com is the new site for the "master" network. However I know that I will need to have one or more subdomains in the future, i.e.;
- <subdomain1>.<DomainName>.com
- <subdomain2>.<DomainName>.com
However when I add a new site, my option for the new site path is <subdomain2>.<subdomain1>.<DomainName>.com, instead of <subdomain2>.<DomainName>.com.
If i change this:
define('DOMAIN_CURRENT_SITE', '<subdomain>.<DomainName>.com'); to <DomainName>.com, it obviously breaks because the <DomainName.com> is not a multisite.
I have to admit, i'm note entirely well traveled in this area and it seems to be a bit of niche, but I'm hoping somebody has had the same – and maybe now a solution.

you might be able to accomplish this with some domain mapping and clever DNS entries, but it’ll be a slog. the best bet is to make the root domain the “main” site, even if that isn’t what you want to use. you can always redirect the root to one of the subdomains if you wanted.
