How to Use an SSL certificate for WordPress Multisite

If you want to enable HTTPS everywhere, then there are simple steps that can make your multisite network secure with robust SSL certificate. This will activate SSL across the network.

  • Browse Network Admin dashboard, click on setting where you will have Domain Mapping option, scroll down the section “Force http/https (Only for original domain).
  • Select “Yes” option that will enable https on login and admin pages.
  • There is a second label named “force https or http for front end pages” where you have to select Force https. It means your main website and it’s all web pages are secured with SSL and URLs occurring with HTTPS in the browser address bar indicates that the website has the highest level of security.
