<iframe src="https://path/to/site" width="300" />
My existing site is also over https.
But i get the error
Mixed Content: The page at 'https://path/to/site' was loaded over HTTPS, but requested an insecure resource 'http://path/to/site'. This request has been blocked; the content must be served over HTTPS.
But the src has https in the iframe.
How to resolve this?
