Broke HTTPS. wasted days on it

Spent days working on a HTTPS error mixed content on my site, stripped it down to no widget and no plugins, deleted content..in the end it turned out to be the POINT theme that was breaking my HTTPS, I even have .htaccess redirect and WordPress HTTPS plugin installed, but once I change from this theme “default install right now no changes” HTTPS works, back to this theme HTTPS breaks, it does not appear to be anything obvious.
