Prestashop 1.7.7.3 update problems

[leloftniv]

Dear,

 

I updated the webshop from work but I can see a infinite loading on orders. (see picture) and, when an order is done, prestashop thinks the order was paid by promo code AND credit card. And it thinks that I want refund the customer. BUT it isn't... 

 

Could you help me ?

 

Thanks
