If your site is using AJAX, you can also install this plugin https://wordpress.org/plugins/wpc-ajax-add-to-cart/ to assist the AJAX loading on your site. It's easy and simple, with no special settings required. Just 1-click installation.
Since not all themes and plugins are integrated with the standardized AJAX for the Add to Cart button, we have developed a plugin for our own WPC users to make sure it has what it needs to work properly. Please install then clear both your site and browser's caches/cookies before checking again.
After receiving your feedback, I'll guide you further if that doesn't help.
Actually I figured out the problem, somehow it was in http, not in https, when I loaded the site in httpS it works fine...
