I updated the domain mapping plugin today. Since then I am no longer able to make the domain mapping domains stick on https://
I can SELECT the https:// option in the Domain Mapping Dropdown menu. But when I click the "MAP DOMAIN" submit button it adds it as http:// in the list above. Which breaks then breaks site, because it NEEDS to be https://.
It was working just fine until I updated today the Domain Mapping plugin today. Then it instantly broke.
ALSO - A VERY Weird thing that might provide a clue... If I use an INVALID domain...then it will save the https:// option. For instance if I choose https:// then enter scoobydoo.mydomain.com it adds it above as https://scoobydoo.mydomain.com.
However, if it's a VALID domain...and I choose https:// then enter http://www.mydomain.com, it will only add it above as http://www.mydomain.com. There is no way to make it stay https:// after I hit the "Map Domain" button.
