SSL for mapped subdomains in multisite (no plugins)
WP multisite network based on subdomains, and domain mapping to my customer domain names without a plugin (I’m on WP 4.6.x).
SSL cert for the server, so the base network domain does come up with green padlock — but I do not cover my customer’s domains – they currently get forced to http.
I need to have all my customer’s domains come up with https, green padlock — without having to install a separate SSL cert for each domain. What is the best way to approach this?
