Brief
We have updated the file 'shopping_cart.php' for version 3.6.
 
Description
When an option 'apply discount for invited friends' was selected together with the option Apply to all friends visits, the coupon could be applied for all users (not only for those who come from the friend's link).
 
Solution
We would recommend you to download an updated version of the file from here:

Further, extract the above mentioned file into the 'includes' folder of your shop in the Binary mode. Do not forget to make a backup copy of the current file in case something goes wrong.
