WP-eCommerse is has an error when "empyt cart" is clicked

Hello, I discovered today that when I click on the link in the sidebar that says “empty cart, I get this error:

`{“widget_output”:”\n\t

Your shopping cart is empty<\/p>\n\t

\n\t Visit the shop<\/a>\n\t<\/p>\n\n”,”core_images_url”:”https:\/\/kraftwerkk9.com\/wp-content\/plugins\/wp-e-commerce\/wpsc-core\/images”,”sliding_cart_state”:”hide”}`

I tried to switch to the 2014 theme and the same issue is there. I tried disabling the cart and enabling it and that didn’t solve it either (although it caused another problem where the checkout page now displays the home page, I will make another thread for that)

The site is https://www.kraftwerkk9.com

I did see another closed thread that had this issue exactly, but it was not resolved.
