Redirect all traffic to the secure version of your site.
Every plan includes a free SSL certificate that is issued automatically once your domain points at our servers.
Once issued, enable Force HTTPS Redirect in cPanel's Domains section. This adds the redirect at the server level, which is faster than a plugin.
For WordPress, also update the Site Address and WordPress Address settings to use https:// so internal links do not create mixed-content warnings.
Finally, re-crawl your site or run a mixed-content scan to confirm every image, script and stylesheet is loading over HTTPS.
