Div of widget Basket stays empty

Hello,

Recently I’ve updated the Woocommerce plugin on our development platform (2.6.8). We are facing the following problem:

– The widget ‘Woocommerce Cart’ has changed its name to ‘Woocommerce Basket’
(This is not a problem, but I cant find anything about it in the changelogs)

– The widget is empty. The div class is not filled with any products, although we have selected some products for the cart:
<div class=”widget_shopping_cart_content”></div>

What is the problem en how can I fix this? I already deactivated all plugins and themes.

Note:
The website is available on our development platform. This has been secured by a username and a password. Please email me for the information.
