Multisite w/Domain Mapping Plugin Confused about SSL Admin – makes all links SSL

It’s good practice to always access the WordPress dashboard over SSL for security whenever possible.

We’ve been doing this in standalone WordPress for years, and in several WordPress MultiSite installs (directory-based) for over a year, with no issues at all. All updated to the latest version, and no issues at all.

However, we recently installed a new domain-based WordPress MultiSite, using the domain mapping plugin, and have several sub-sites running great on it, domain mapped. Been working great in production for over a month.

EXCEPT an odd issue with managing WordPress over SSL…

In the new domain-based MultiSite, if I’m logged in over SSL, WordPress seems to think that the actual public website is SSL too

For example, I create a new post, and at the top of the post edit page, it shows me the post Permalink as “https://”.

I click Preview or “view post” and it opens the post with the https:// URL… SSL.

But in all our other WordPress installs, both standalone AND directory-based MultiSite, while of course still logged in over SSL, I go create a new post, and at the top of the post edit page it shows me the regular Permalink, i.e. “https:// “

So with directory-based MultiSite (or WordPress standalone), it doesn’t get confused and think that suddenly the whole site is SSL just becasue I’m editing it over SSL. ??

I’ve looked for others having this problem, and found this old support post was referring to a similar issue (rather a symptom of the same problem lol), but it’s closed (though not resolved).

Does anyone have any idea why a domain-based MultiSite would be having this problem – confusing the production site as being SSL just because you’re logged into the admin over SSL??

Thanks!
