WordPress-Specific SSL Installation

WordPress powers over 40% of the web, making WordPress-specific SSL installation knowledge invaluable. While SSL installation occurs at the server level, WordPress requires additional configuration to fully utilize HTTPS. Modern WordPress hosting providers often handle SSL installation automatically, but understanding the complete process ensures proper implementation and helps troubleshoot issues.

For managed WordPress hosts like WP Engine, Kinsta, or Flywheel, SSL installation typically involves just clicking a button in your hosting dashboard. These providers have streamlined the process to handle server configuration, certificate installation, and WordPress configuration automatically. Navigate to your site's settings in the hosting dashboard, find the SSL or Security section, and enable SSL. The host handles certificate provisioning (usually through Let's Encrypt), installation, and automatic renewal.

After installing the certificate at the server level, WordPress needs configuration updates to use HTTPS URLs throughout your site. Install a plugin like "Really Simple SSL" or "WP Force SSL" to handle this transition automatically. These plugins detect your SSL certificate, update your WordPress URLs, fix mixed content issues, and implement proper redirects. Alternatively, manually update your WordPress Address and Site Address in Settings > General to use https://, update your wp-config.php file with proper constants, and implement .htaccess redirects.

Common WordPress SSL issues include mixed content warnings from images, scripts, or stylesheets still loading over HTTP. Use your browser's developer tools to identify these resources and update their URLs. Some themes and plugins may have hardcoded HTTP URLs requiring updates. Database search-and-replace tools can help update URLs in your content, but be cautious with serialized data that can break if incorrectly modified. Always backup your database before making bulk changes.
