Redirect my WordPress website to HTTPS in cPanel hosting
If you have a secure certificate (SSL) on your WordPress website, you can automatically redirect visitors to the secured (HTTPS) version of your website to make sure their information is protected.
Note: Several plug-ins are available for WordPress that can redirect your URL automatically after you have installed your SSL certificate. For help with WordPress plugins, see wp.org
Warning: These instructions do not apply to SSLs installed on Managed WordPress. The HTTPS redirect is automatically enabled after the SSL certificate install finishes on a Managed WordPress account.
