After all, I am finally able to create a multisite on my domain here.
I created a subdomain of that multisite See the image →
but the site is hosted on the HostGator, and the sub-domain was not already created, but while creating the sub domain I came across a situation where I got confused the HostGator is asking for the document root? what document root should I give since the sub-domain has already been created so I guess the multi site WordPress has created a root. isn't IT?
I think since in multi site the database is same so the root should be the same of the primary or the first site?
Please guide me.
