woocommerce cart empty issue

Hello,
My site is using Vietnamese language. After update to 4.3, I’ve yet to get Woocommerce to add any product to my shopping cart. It redirects me to the page and displays “Your Shopping Cart is Empty”. But if I switch to default language (English: http://i.imgur.com/Kw2GFMS.png ), the cart work normally ( products added ) .
Please help me how to fix the problem.
Thanks
