WordPress Multisite often called WordPress Mutlisite Networks. It helps you to manage more then one WordPress at a single dashboard so one can easily manage more then one site and saves tons of time.
It helps to post on various blogs as well manage the contents on various networks with domains and sub-domains.
Let’s do step by step and understand domains and subdomains with the same network.
Got to your “wp-config” and insert the code at the bottom or before happy blogging
/* Multisite */
define( ‘WP_ALLOW_MULTISITE’, true );
Once you do that it will open network into your WP-Dashboard area under the tools where you need to deactivate and activate WordPress Plugins to enable them with the respective networks or subdomains or domains.
Once you do that, you might need to follow some editing your WP-Config and .htaccess files and re-login to your dashboard.
Once you are able to relogin, you can see the Network option at top left corner and that will help you to add domains and subdomains to your multisite networks.
