Multi-site Installed but New Sub-domains are not being created

Have you correctly set up Wildcard Subdomains? This looks like a DNS issue.

Network Error (dns_unresolved_hostname) accessing ” https://one.mxlmicrophones.org/”

Yep, DNS.

OK thanks, but I have no idea how to fix this. Can anyone help? Do I do this from my cPanel, if so how? Keep in mind that I am a novice.

I think I figured out the DNS issue, I set up a wildcard subdomain thanks to Bluehost tech support. Now all it does is show the bluehost page:

https://test.mxlmicrophones.org/

Any other suggestions?

Where did you point your wildcard domain? It should be pointing to whereever you have WP installed. Normally that’s /public_html

As Ipstenu said, your installation appears to be on mxlmicrophones.org and thus your wildcard subdomain should be setup directly to the root of the mxlmicrophones.org domain. If it is your primary domain, it will be public_html.

You can use the Subdomains icon in your cPanel to delete any current wildcard subdomains, and re-create them to point to the document root of /public_html/

If this is for a domain other than your primary domain, then the document root will be something like /public_html/yourotherdomain
(replaying yourotherdomain with the real folder where your domain is actually assigned-to/setup at.)
