We have multisite set up to use subdomains. Dangeroustactics.com is primary domain. newthoughtforum.dangeroustactics.com is a subsite. We've successfully mapped newthoughtforum.com as the domain for this site. Everything was working great until I installed SSL. There is a shopping cart, so the site requires it.
Some browsers are not displaying some of the page elements, while others are still saying the site is not secure, even though I've confirmed that certificate is installed properly.
After looking into it further, I've verified that all queries involving the mapped domain (newthoughtforum.com) are rendering properly via https. However, there are still page elements being called through the subdomain (newthoughtforum.dangeroustactics.com). The fact that every page of the site is delivering mixed content (both secure and not secure) is causing issues with how the site works.
Does the domain mapping plugin not work on all page elements? Is domain mapping plugin installed or configured incorrectly? How are people running SSL in this type of setup? Am I required to have two certificates, one for the subsite's domain and another wildcard for the entire primary domain and all subdomains? In other words, do I need to have a separate certificate for the subdomain in order to have a secure subsite on this multisite?
Support access is enabled. I'm happy to provide any details necessary. Any insight is much appreciated.
