Allow Wildcard SSL Certificate to be used across multiple applications
Currently you can only use a wildcard SSL certificate with one application, which limits its usefulness to a multi-tenant web application like WordPress Multisite.
If you setup a second application that uses a subdomain that would be covered under your wildcard SSL you unfortunately cannot use the wildcard cert.
As an example:
Application 1 has the domain example.com and a wildcard certificate *.example.com
Application 2 has the domain forum.example.com
Application 2 should be able to use the wildcard certificate from Application 1.
If they are not allowing then you can use cloud flare and really simple ssl plugin to enable SSL on your website. I also did the same thing for my website https://www.melbourneosteopathycentre.com.au/. If you need any information about it you can ask it from me.
