How can I automatically redirect HTTP to HTTPS?

After installing your SSL, you must enforce an HTTPS redirect. By adding a 301 redirect rule to your server (e.g., editing the .htaccess file), all traffic will be automatically routed to the secure HTTPS connection without needing manual URL updates.

How to fix the 'Not Secure' or Mixed Content warning?

If your SSL is active but the browser still shows a warning, you likely have 'Mixed Content'. This means your secure HTTPS page is loading insecure HTTP resources (like images or CSS). You must update all internal links to use 'https://' to restore the secure padlock icon.

Wildcard SSL Certificate (DV)

Q: Is a Free SSL just as good as a Paid Wildcard SSL?

For wildcards, paid is much better. While Free SSLs (like Let's Encrypt) offer wildcard options, they enforce strict DNS-01 challenges that are difficult to automate and expire every 90 days. A Paid Wildcard SSL offers simple email/DNS validation, lasts up to 200 days, and includes high commercial warranties.

Q: How do I generate a CSR for a Wildcard SSL?

You can easily generate a CSR via your hosting control panel (e.g., cPanel). CRITICAL: When entering your domain name (Common Name), you MUST use an asterisk before your domain (e.g., *.yourdomain.com) so the certificate applies to all subdomains.

SSL Certificate FAQ

Q1: What is a Wildcard SSL Certificate?

A Wildcard SSL Certificate secures your primary domain (e.g., yourdomain.com) and all first-level subdomains under it (e.g., *.yourdomain.com including shop.yourdomain.com, blog.yourdomain.com) using only one certificate. It is the most cost-efficient choice for businesses with multi-system architectures.

Q2: Is a Free SSL just as good as a Paid Wildcard SSL?

While both provide standard encryption, Free SSL certificates expire every 90 days and offer no commercial warranty protection. Paid Wildcard certificates from major CAs like Sectigo, Certum, and GeoTrust provide longer validity, commercial warranty backing, official site seals, and recognized browser trust.

Q5: How can I force an automatic HTTPS redirect?

Once your SSL is installed, you must configure a server-side 301 redirection rule (e.g., editing the .htaccess file). All traffic will automatically route to the secure HTTPS connection without needing manual URL updates across your site.

Q6: Why is the secure padlock icon missing on my website?

If an SSL certificate is active but the browser does not display the secure padlock, the page is likely experiencing a "Mixed Content" issue where resources (images, CSS/JS files) are loaded over insecure HTTP protocols. Updating all internal asset URLs to "https://" will resolve the warning.
