Domain Mapping and Wildcard SSL Certs on a Multisite

Hi,

I have installed a Wildcard SSL cert for my Wordpress Multisite- http://facebook.etownz.com. The name of the wildcard domain was *.etownz.com. https://www.sslshopper.com/ssl-checker.html#hostname=facebook.etownz.com

I have used the domain mapping plugin to change a sub-directory install to http://lennonsbardurrow.com, however, the Wildcard SSL doesn't seem to cover this, and I can't purchase an SSL for the domain http://lennonsbardurrow.com, as I was told this would not work; it would need to be under a Wildcard cert.

We are attempting to insert the Wordpress site into a custom application on a facebook business page, so the website is available directly from there, and facebook require you to have a SSL cert to insert into a page- https://www.facebook.com/pages/Lennons-Bar-Venue/833574373388392?sk=app_839906129433838.

Should this be working? I'm unsure how to do this correctly.

Best,
Mark
