Prestashop 1.4.8.2
The back office option to "display tax in cart" (payment>taxes) does not work.
The tax is displayed in the cart regardless of whether the option is checked or not in the back office.
To make the tax show or not i have to edit the shopping cart .tpl file directly each time to hide the rows, it's frustrating.
How can i make the back office option work properly?
