> Failed to execute 'postMessage' on 'DOMWindow': The target origin provided
('https://app.kissmetrics.com') does not match the recipient window's origin
(Note: stage.acme.com is not the real host name, obviously. Everything else is pasted as-is.)
This error comes from a file whose url is https://widget.cloudinary.com/n/ourcloudname/136/index.html?cloud_name=ourcloudname (Note: here too, ourcloudname is not real)
I also found a post on StackOverflow related to this kind of error: https://stackoverflow.com/questions/27573017/failed-to-execute-postmessage-on-domwindow-https-www-youtube-com-http However the problem appears to be with mixing http and https, and we don't, everything is https.
So I don't see how to solve this problem. Is there anything that we could check to try and get rid of this error?
