You installed an SSL certificate, changed your WordPress URL settings to ' + "'https://'" + ', but your browser still refuses to show a secure green padlock icon - instead displaying a warning: "Your connection to this site is not fully secure."
This frustrating issue is known as a Mixed Content Error. It occurs when your primary HTML page loads securely over HTTPS, but older images, CSS stylesheets, or external scripts are still being requested over insecure ' + "'http://'" + ' protocols. Here is how to fix mixed content warnings permanently in 2026.
Step 1: Identify the Insecure Assets
Before fixing the issue, identify which specific files are causing the warning:
- Open your website in Google Chrome.
- Right-click anywhere on the page and select Inspect (or press 'Ctrl+Shift+I' / 'Cmd+Option+I').
- Click the Console tab.
- Chrome will highlight mixed content errors in red or yellow text, showing the exact URL: > Mixed Content: The page at 'https://example.com' was loaded over HTTPS, but requested an insecure image 'http://example.com/wp-content/uploads/banner.jpg'. This content should also be served over HTTPS.
Step 2: Fix URLs Across Your Entire WordPress Database
The most reliable, permanent solution is updating old hardcoded ' + "'http://'" + ' links in your MySQL database:
- In your WordPress admin dashboard, install the free Better Search Replace plugin.
- Navigate to Tools > Better Search Replace.
- In the Search for field, enter: ' + "'http://yourdomain.com'" + ' (replace with your actual domain).
- In the Replace with field, enter: ' + "'https://yourdomain.com'" + '.
- Select all tables ('Ctrl+A' or 'Cmd+A').
- Uncheck the "Run as dry run" box and click Run Search/Replace.
- The plugin will update thousands of image paths and internal links in seconds without corrupting serialized PHP data.
Step 3: Enforce HTTPS Redirects in .htaccess
Prevent any visitor from accidentally loading the insecure version by adding a 301 permanent redirect rule to your root '.htaccess' file:
'''apache
Clear your browser and server cache, and your green padlock will shine immediately.
