Why SSL/HTTPS Matters in WordPress

SSL (Secure Sockets Layer) ensures that the connection between your website and your visitors’ browsers is secure. Without it, sensitive data like passwords, payment details, and personal information could be intercepted.

• ✅ Builds trust with your audience
• ✅ Improves your website’s SEO rankings
• ✅ Essential for eCommerce and login-based sites
• ✅ Prevents “Not Secure” warnings from browsers

Common SSL/HTTPS Login Issues in WordPress

After activating an SSL certificate, many WordPress users experience these problems:

1. Endless redirect loops (site keeps refreshing)
2. Mixed content warnings (some elements still load via HTTP)
3. Unable to log in – login page not loading properly
4. “Too many redirects” error message
5. Broken CSS or JavaScript after switching to HTTPS

Step 1: Update WordPress Address & Site Address

The first step to solving HTTPS login issues is to update your WordPress URL settings.

Method 1: Update from WordPress Dashboard

1. Log in to your WordPress admin dashboard.
2. Go to Settings → General.
3. Update both fields:
   • WordPress Address (URL)
   • Site Address (URL)
4. Change http:// to https://.
5. Click Save Changes.

Method 2: Update via wp-config.php

If you can’t access the dashboard, update the URLs manually:

define('WP_HOME','https://yourdomain.com');
define('WP_SITEURL','https://yourdomain.com');
    

Method 3: Update via Database (phpMyAdmin)

1. Login to your hosting control panel.
2. Open phpMyAdmin and select your WordPress database.
3. Find the table wp_options.
4. Edit the values for siteurl and home.
5. Replace http:// with https://.

Step 2: Redirect All Traffic to HTTPS

Even after updating WordPress and Site Address, some pages may still load via HTTP. To fix this:

Edit .htaccess File

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
    

Step 3: Fix Mixed Content Issues

Mixed content occurs when some resources (images, CSS, JS) load via HTTP. To fix:

• Install a plugin like Really Simple SSL.
• Manually update hardcoded URLs in your theme or database.
• Use a search-and-replace tool to change all HTTP links to HTTPS.

Step 4: Clear Cache & Cookies

Sometimes, browsers cache old URLs. Clear:

• WordPress cache (if using plugins like W3 Total Cache, WP Rocket)
• Browser cache and cookies
• CDN cache (if using Cloudflare or similar services)

Step 5: Test Your SSL Setup

After making the changes, test your site with:

• SSL Labs Test
• Browser console (check for mixed content errors)
• Try logging in/out multiple times to confirm no redirect loops

Bonus Tips for Secure WordPress Login

• Always use the latest version of WordPress and plugins
• Enable two-factor authentication (2FA) for extra security
• Use strong, unique passwords
• Install a security plugin like Wordfence or iThemes Security

Conclusion

Fixing SSL/HTTPS login issues in WordPress may seem complicated, but with the right steps, it’s a straightforward process. By updating your WordPress Address and Site Address, setting up redirects, fixing mixed content, and clearing cache, you can ensure your website runs smoothly on HTTPS.
