Even though you have an SSL certificate for your website, your visitors will not use HTTPS while accessing your website by default.
You can simply fix that following these steps:
- open your hPanel;
- click on SSL at the top of the page;
- click Manage;
- select Force HTTPS!
- ...aaand you're done!
IMPORTANT: If you do not have a valid SSL certificate installed, your website can become inaccessible due to this redirection. To make sure, that everything will be working correctly, simply access your website by typing "https" in front of your web address manually :)
