Your free SSL is included, so this is mostly a settings change.
- Confirm SSL is active in cPanel under SSL/TLS Status (use Run AutoSSL if needed). New certificates issue automatically.
- In WordPress go to Settings > General and change both WordPress Address and Site Address to
https://yourdomain.com. - Install a plugin like Really Simple SSL to redirect all traffic to https and fix internal links automatically.
To force https without a plugin, add a redirect rule to your .htaccess. After switching, clear LiteSpeed Cache and your browser cache, then test pages for mixed-content warnings (see our separate guide). If SSL won't issue because DNS hasn't propagated, wait a few hours or open a ticket.
