Thanks for your reply.
first let me tell you about my instance
its aws windows server 2016 micro instance in free tier.
I had installed bitnami wordpress multisite stack 4.9.5-2 version with blog name as GEETA MART and server name as localhost. and updated to 4.9.6
i want to start multivendor based B2B and B2C online pharmacy.
i Had gone through this documentation,
added sub domains as mentioned via
my sites> network admin> sites
but unable to see my new subdomain in the drop down list of my sites
when going through all sites> list of sites> new subdomain name is present
when clicking on visit site/dashboard> following is the error shown in firefox
now as mentioned in documentationIf you're in a hurry, or just testing things out, you can instead modify your local hosts file to map each subdomains to your server's IP address. For more information on both these options, refer to the section on testing your installation. The shortcut involves manually adding entries for your domain(s) and subdomain(s) in your local system's hosts file, which is always checked before a query is sent to a DNS server.
my question: which host file to modify? and what content to modify?
I want to test the site with local files first and then i will add actual subdomains in it.
i had used the support tool and code is shown below
kindly go through it and help me out
thanks and reagrds
