Woke up this morning without having changed a thing in MB or my cam upload url which is an https:// but with older versions of MB had to use http:// as it would not work.
Back to the first sentence, I didn't change a thing and it is working. After banging my head trying to find an older version that worked and giving up for the day... This morning it is back to normal so Problem is "SOLVED"
