Step-by-Step Guide: How to Fix Mixed Content Errors

Here’s a straightforward breakdown of resolving mixed content errors. Each step is carefully curated using industry knowledge and tools to ensure an expert-level guide to resolving this issue.

Step 1: Identify Mixed Content Problems

Tools You May Need:

  1. Browser Developer Console: Open your site in any modern browser (e.g., Chrome). Press F12, go to the Console tab, and look for any warnings labeled “Mixed Content.”

  2. Online Scanning Tools: Use tools like Why No Padlock or SEMrush’s Site Audit Tool to detect insecure elements.

  3. Install Plugins: For WordPress websites, install the SSL Insecure Content Fixer plugin.

    Affiliate Opportunity: Consider pairing this with additional helpful tools like EaseUS Backup Center to back up your site before making changes.

Step 2: Ensure Your Website is Fully HTTPS

  1. Secure an SSL Certificate
    Obtain an SSL certificate from free providers like Let’s Encrypt or a paid solution if you require extended validation. Most hosting providers offer simplified SSL setup via their dashboards.

  2. Verify the SSL Certificate
    Visit your site. Check the padlock icon in the address bar:

    • If it shows a warning, ensure the domain is properly added during your SSL setup.
    • Tools like SSL Labs can thoroughly analyze your SSL configuration.

    💡 Pro Tip: Use managed WordPress hosting that automatically handles SSL renewals to save time.

  • Replace all instances of http:// with https:// in your site’s code.

  • This applies to:

    • Navigation menus
    • Embedded CSS and JavaScript files
    • Image files (src attributes)

    How to Execute:

    • Use a WordPress plugin like Better Search Replace for bulk updates.
    • Alternatively, run database queries such as: 
      UPDATE wp_posts SET post_content = REPLACE(post_content,'http://','https://');

If your pages rely on external HTTP resources:

  1. Reach out to resource owners to request HTTPS support (CSS libraries, scripts, etc.).

  2. Download the files to your server to host them locally.

  3. Replace external links with local paths (or HTTPS versions).

    🚩 Expert Warning: Beware of caching plugins like Cloudflare aggressively serving cached HTTP content. Clear your cache after updates.

Step 5: Implement Relative URLs

Use relative URLs for internal resources wherever possible. Instead of:

<img src="http://example.com/images/logo.png">

Use:

<img src="/images/logo.png">

Why It’s Effective?
A relative URL adapts automatically to the protocol (HTTP/HTTPS) being used, ensuring a consistent secure load.

Step 6: Deploy Content Security Policy (CSP)

Add the following code to your .htaccess file or server configuration:

Header always set Content-Security-Policy: "upgrade-insecure-requests;"

This helpful snippet instructs browsers to attempt upgrades for all HTTP requests to HTTPS counterparts, automatically reducing mixed content warnings.

Step 7: Automate Fixes with Plugins

WordPress plugins like SSL Insecure Content Fixer offer automated corrections for mixed content errors across different elements.

Plugin Modes:

  • Simple (basic fixes for most websites)

  • Capture All (captures all possible sources of mixed content)

    Using a different CMS? Drupal and Joomla also offer similar plugins for fixing mixed content. Always ensure compatibility.

Step 8: Regular Testing & Monitoring

  • Website Testing: Visit your pages in multiple browsers to confirm the fixes are effective.

  • Monitoring Tools: Set alerts through services like Pingdom or Google Search Console for recurring SSL certificate issues and new mixed content warnings.

    🛠 Expert Suggestion: Implement Uptime Monitoring to quickly identify issues with SSL misconfiguration. Pair tools like Cloudflare with EaseUS LockMyFile for enhanced data protection.
