Mixed content occurs when an HTTPS page loads one or more resources over insecure HTTP. The page certificate can be valid while the browser still blocks or warns about those resources.
- Open the page using HTTPS.
- Use the browser developer tools or console to identify HTTP resources.
- Update image, script, stylesheet, iframe, or application URLs to HTTPS where the resource supports it.
- Clear application and browser caches and retest.
Installing another certificate will not fix hard-coded HTTP resource URLs.
