I've successfully installed an SSL certificate on my host, but I can't seem to get this plugin to work.
My test page is https://portlandrescuemission.org/ssl-test/
Depending on the browser, I get different error messages. But the basic error seems to be a server communication error / unable to establish a secure connection to the server.
I'm using port 443 and confirmed with my web host that this is the correct setting.
Not sure what to do.
