You activate WP Force SSL to make your site secure. Now your site has mixed content warnings. Images, CSS, or JavaScript load over HTTP. Browser shows “not fully secure.” That is frustrating because SSL should fix everything.
A common issue is that WP Force SSL redirects pages to HTTPS but does not rewrite content URLs. Your database still has HTTP URLs in posts, widgets, and settings. The plugin is not broken. You need to update database URLs.
Why Mixed Content Happens After WP Force SSL
WP Force SSL forces HTTPS at server level. When browser loads your page, it uses HTTPS. But your page content (images, CSS, JS) still references HTTP URLs from database. Browser blocks these mixed content requests. The plugin cannot rewrite URLs stored in database automatically.
This is not WP Force SSL being bad. Database URLs must be updated separately.
The Most Common Mixed Content Sources
- Images in posts and pages (stored as HTTP)
- Logo and site icon in theme settings (stored as HTTP)
- CSS background images (hardcoded in theme files)
- External scripts loaded over HTTP
- Widget content with hardcoded HTTP URLs
Each source needs separate fix.
How to Fix Mixed Content After WP Force SSL
- Install Better Search Replace plugin
- Search for “http://yoursite.com”
- Replace with “https://yoursite.com”
- Run on all database tables
- Check “Dry run” first to preview changes
- Clear all cache
- Test site for mixed content warnings
Updating database URLs fixes most mixed content issues.
How to Check for Mixed Content Issues
Open browser developer tools (F12) → Console tab. Look for “Mixed Content” warnings. Also check Network tab for HTTP requests. Each HTTP request is a mixed content warning. Fix each URL by updating to HTTPS.
Browser console tells you exactly which files are causing problems.
Alternative: Use SSL Insecure Content Fixer Plugin
Install SSL Insecure Content Fixer. It rewrites content URLs on the fly. No database changes needed. Enable “Capture” mode. Mixed content warnings disappear instantly.
This is temporary fix. Database update is permanent fix.
