Hello,
I have same problem. I am using prestashop 1.6.0.14 for 4 shops and all have same issue.
The problem is in creating order from backoffice.
1. go to orders
2. create order
3. look for customer, select customer
4. search for product
5. add product -> Nothing is added 6. Change address -> Nothing happens
When I repeat the steps the changes are there, it means it saving changes I made but not displaying. 7. click again orders 8. Create order 9. Select same customer 10. product added to cart will be shown under carts tab. click use to select to proceed with order creation. 11. changed in address are also saved
12. Any new changes made will have to repeat all steps again to see them (orders, create order, select customer,....) Does anyone know the solution for that?
Thank you.
