This is regarding multi site/multi domain configuration.
Primary multisite installtion: Writerswalk.com
alternative domain in multi-domain plug in: scribesites.com
I initially created a wildcard subdomain in cpanel When cpanel asked for the path to the subdomain, it pointed it the WP installtion on writerswalk.com. I also added an A record pointing to the ip address of writerswalk.com.
whatsmydns.net says that my.scribedomains.com resolves.
But the multidomain plugin says the wildcard is unavailable.
I don't know if I am making sense.
Add on information
Even though the multidomain plugin says wild card unavailable, it seems to be working. I am able to create domains with in the network admin area. I can also register using both domains.
So I don't know what I did, but I guess it worked.
So unless someone has insight that might help me understand, I guess the issue is resolved.
