Prestashop網站為每個頁面和每個ajax查詢拋出404個錯誤[版本1.6.1.18]

Url: 420panda.ca

在每個產品頁面上，它加載頁面，但在控制臺中拋出404錯誤。它看起來是這樣的：

當我使用每個產品頁面上的“+添加到購物車”按鈕將產品添加到購物籃時，我也會遇到一個錯誤。錯誤如下所示：

Impossible to add the product to the cart.

我在購物車本身也會出現如下錯誤：

TECHNICAL ERROR: unable to save update quantity Details: Error thrown: [object Object] Text status: error

看起來每個AJAX調用都會返回一個錯誤，但我找不到源。有什么想法嗎？
