  • Adds Content-Security-Policy: upgrade-insecure-requests header if on HTTPS
  • Redirects to HTTPS if not on HTTPS and the browser sends HTTP_UPGRADE_INSECURE_REQUESTS header.

This is a simple, no-config plugin with focus on short, high quality code.

I installed all the popular plugins available to fix my HTTPS mixed content problem, then I tried yours last and it’s the ONLY ONE that fixed my site! I would have saved hours of my time if I had tried your plugin first! Thank you!
