WordPress Multisite, Domain Mapping, SSL

Hi,

I’ve done some searching but couldn’t find this issue elsewhere, apologies if this has already been discussed elsewhere.

I’ve set up a Multisite install; and am trying to set up domain mapping for sub-sites. The main site has wildcard SSL enabled and WP Admin forced to SSL.

The issue is that the mapped domains do not have SSL, links in WP Admin to the frontend show as https:// even when the home URL is defined without SSL.

e.g.

Site URL https://sub.multisite.com/
Home URL: http://sub.com/ (but shows in WP Admin as https://sub.com/ e.g. the “Visit Site” link)

I’ve tried using the WordPress MU Domain Mapping plugin and Mercator (https://github.com/humanmade/Mercator) to achieve this, both without success.

WordPress.com has a similar setup but does appear to work (mapped domains don’t need SSL and the links from WP Admin are correct); I presume this is a custom solution.

Does anything exist that addresses the issue of SSL with mapped domains?

Thanks,

James
