Don't get the sale order by calling website.sale_get_order(). It is already give in the value to render the template. You can fix this old mistake : go to controller/main.py, in `def cart(self, **post)`. In value dict, rename the `order` key into `website_sale_order` (to minimize the diff), then remove `<t t-set="website_sale_order" t-value="website.sale_get_order()"/>` in the template. Thanks.
