Tool guide

Fixing mixed content and HTTPS asset issues

Mixed content happens when an HTTPS page still loads images, scripts, styles, forms, or canonicals over insecure HTTP.

What this tool does

It scans fetched HTML for insecure HTTP references in common attributes and CSS URL patterns.

Who it helps

  • Site owners seeing browser lock warnings
  • Developers after SSL migration
  • SEO teams checking canonical and asset hygiene

Usage instructions

Enter a page URL. Review the listed HTTP assets and update them to HTTPS, relative URLs, or the correct CDN URL.

Understanding the output

HTTP scripts and forms are highest priority because browsers may block them or expose user data. Image warnings are still worth fixing for trust and consistency.

Why it matters for hosting

Mixed content often appears after SSL activation, CDN changes, WordPress migrations, or hardcoded theme/plugin URLs.
