No Comments

Quick Reference

Element Code: SE-010

Issue: HTTPS page loads resources over insecure HTTP

Impact: Browser warnings, potential security vulnerabilities

Fix: Update all resource URLs to HTTPS

Detection: Browser console, security audits, Screaming Frog

What Is This Issue?

Mixed content occurs when an HTTPS page loads images, scripts, or other resources over HTTP. This undermines HTTPS security and causes browser warnings.

Why This Matters for Your Website

Mixed content can be intercepted and modified. Browsers increasingly block mixed content, breaking page functionality.

How to Fix This Issue

  1. Find mixed content: Check browser console for warnings
  2. Update URLs: Change http:// to https://
  3. Use protocol-relative: Or better, always use https://

Tools for Detection

  • Browser console: Shows mixed content warnings
  • Screaming Frog: Finds HTTP resources

TL;DR (The Simple Version)

Your HTTPS page loads some content over HTTP. Update all resource URLs to HTTPS to maintain security and prevent browser warnings.
