SSL connection in Opencart?

I want to enable SSL connection in Opencart. Can anyone tell me how should I do that?

1. Ask your web host to install an SSL certificate for you. It usually costs between $50 and $100 per year.

2. Turn on SSL in System > Settings > Server.

3. Check your URLs in the /config.php and /admin/config.php files, right at the top of those files. For the ones starting with "HTTPS_", make sure they are https:// URLs.

And if you want to save some money, you can also use a free SSL certificate, for example, Let’s Encrypt.
