Mixed Content Error

If you’re getting a Mixed Content error:

Mixed Content: The page at 'https://yoursite.com/cp/collections/entries/stores' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://yoursite/cp/collections/entries/stores/get?sort=title&order=asc&page=1'. This request has been blocked; the content must be served over HTTPS.

when accessing your control panel, add use_https: true to your system.yaml. Also ensure your site url has https in it.

If your assets have absolute URLs, HTTPS=on should be added to .env.
