After your SSL is active, redirect all traffic to HTTPS so visitors always use the secure version. The easiest way is in cPanel > Domains, where you can toggle Force HTTPS Redirect for each domain.
For full control, add this to the top of your .htaccess file in public_html:
- Open File Manager and enable Show Hidden Files.
- Edit
.htaccessand add:RewriteEngine OnRewriteCond %{HTTPS} offRewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]
WordPress users can simply set both URLs to https://yourdomain.com under Settings > General. Clear your cache and test in a private browser window.
