How do I enable HTTPS for WordPress?

Understanding HTTPS and SSL

HTTPS (Hypertext Transfer Protocol Secure) encrypts data between your WordPress site and visitors' browsers. This is critical for security, SEO rankings, and user trust. At HostingDuty, we include free SSL certificates with every hosting plan because we believe security should be standard, not optional.

Prerequisites for HTTPS

Before enabling HTTPS, you need an SSL certificate. You have three main options:

1. Let's Encrypt: Free, automated certificates that require renewal every 90 days. We automate this process on our servers so you never worry about expiration.

2. Paid SSL: Extended validation certificates from providers like DigiCert or Sectigo. These provide additional verification and longer validity periods.

3. HostingDuty Free SSL: All WordPress sites on HostingDuty automatically receive SSL certificates through our control panel. No manual installation required.

Implementation Steps

Step 1: Install SSL Certificate

If you're using HostingDuty, navigate to your cPanel or hosting dashboard and locate the SSL/TLS section. Click "AutoSSL" or "Let's Encrypt" to issue a certificate for your domain. For custom SSL certificates, upload your certificate files through the same interface.

Step 2: Update WordPress Settings

Log into your WordPress admin panel and go to Settings > General. Change both the WordPress Address (URL) and Site Address (URL) from http:// to https://. Save changes and log back in. This ensures all future links use HTTPS.

Step 3: Configure 301 Redirects

Add the following code to your .htaccess file to force all HTTP traffic to HTTPS:

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

This ensures search engines and users always reach the secure version of your site. Learn more about .htaccess configuration in our kb/htaccess-ssl-redirect guide.

Step 4: Update Internal Links

WordPress may still generate HTTP links in existing content. Use a plugin like Better Search Replace or the free version of Really Simple SSL to update all internal links. This prevents mixed content warnings where some resources load over HTTP while others use HTTPS.

Common Issues and Solutions

Mixed Content Warnings

If you see mixed content warnings in your browser console, it means some resources (images, scripts, stylesheets) are still loading over HTTP. Update your database to replace all http:// URLs with https://`. Our tutorials/fix-mixed-content-wordpress tutorial walks through this process.

SSL Certificate Expiration

Let's Encrypt certificates expire every 90 days. Set up automatic renewal through your hosting control panel or use a cron job. HostingDuty handles this automatically, so you never experience downtime due to expired certificates.

Browser Compatibility

Modern browsers display a padlock icon for HTTPS sites. If you see a warning, check your certificate chain is complete. Some older browsers may not support certain cipher suites, but this is rare nowadays.

SEO and Performance Impact

Google uses HTTPS as a ranking signal. Sites with SSL certificates may see improved search rankings. Additionally, HTTP/2 requires HTTPS on most modern servers, which provides faster page load times. Learn more about compare/ssl-vs-tls to understand the technical differences.
