Wildcard SSL certificate and Domain mapping – not working on users sites

Hi There,

I recently purchased a wildcard SSL certificate for my multisite network. My aim is to add SSL to all my users’ sites, even though they have mapped domains. I have been reading this post here which gave me hope:

The wildcard SSL is set up on my server and I have changed the settings in my Domain mapping plugin as per the tutorial, however, when I try and force SSL on a page on one of my users sites, I get a Privacy Error from my browser, saying “Connection is not secure”.

So for example, https://mainblog.com works fine, but, https://usersblog.com shows insecure connection error. Have I missed something?
