Hi yellow,
Since I installed SSU, I am facing a problem. When on any product page, "Add to Cart" button is clicked, it takes me to the main page without adding the product to the cart and a message is shown saying "Your Shopping Cart is empty.". What is strange is that the shopping cart works perfectly sometimes but other times no products are added to the cart.

Store url: www.gemsoul.com

Any idea to the root of this problem?

Thanks,
Harshil
