How to configure SSL for OpenCart v.2

To enable SSL in your OpenCart v.2, follow these simple steps

Step1. Activate HTTPS in config files

Edit files /confgi.php and /admin/config.php and ensure the HTTPS_SERVER constant is defined and begins with https://

define('HTTPS_SERVER', 'http://yourdomain.com/');

in the example above the HTTPS_SERVER variable is set to http, which needs to be corrected as below:

define('HTTPS_SERVER', 'https://yourdomain.com/');

 Step 2. Enable HTTPS via OpenCart admin console

Login to your OpenCart admin

Go to OpenCart Setting page to activate SSL

and select the Use SSL radio button:

Save the configuration.

Set OpenCart to load over SSL

To make your entire website loading over SSL, update the HTTP_SERVER constant in your config.php and admin/config.php files. Change it from

define('HTTP_SERVER', 'http://yourdomain.com/');


define('HTTP_SERVER', 'https://yourdomain.com/');

Test your website still loading.
