Can you help me with this:

When I try to change number of products in cart or delete product, the update process is stuck

SOLUTION:
Please go to the file: /domains/YOURDOMAIN/public_html/modules/mod_sj_hk_minicart_pro/mod_sj_hk_minicart_pro.php and find:

$cart->ajaxurl = strtolower(substr($_SERVER["SERVER_PROTOCOL"], 0, 5)) == 'https://' ? 'https://' : 'http://';
$cart->ajaxurl .= $_SERVER['HTTP_HOST'].$linkshopingcart;
=> Edit to:
$http = $_SERVER["HTTPS"] == 'on' ? 'https://' : 'http://';
$url .= $_SERVER['HTTP_HOST'].$linkshopingcart;

$cart->ajaxurl .= $http.$url;
