Fixing Mixed Content Systematically

Systematic approaches efficiently resolve mixed content across entire sites. Start by identifying all insecure resources through browser tools, server logs, or automated scanners. Content Security Policy reports help monitor mixed content:

# CSP reporting for mixed content detection
add_header Content-Security-Policy "default-src https:; report-uri /csp-report" always;

# Upgrade insecure requests automatically
add_header Content-Security-Policy "upgrade-insecure-requests" always;

Update resource URLs from HTTP to HTTPS:

# Find and replace in files
find /var/www -type f -name "*.html" -exec sed -i 's|http://|https://|g' {} +

# Database updates for WordPress
UPDATE wp_posts SET post_content = REPLACE(post_content, 'http://example.com', 'https://example.com');
UPDATE wp_posts SET guid = REPLACE(guid, 'http://example.com', 'https://example.com');
UPDATE wp_postmeta SET meta_value = REPLACE(meta_value, 'http://example.com', 'https://example.com');
