Hello, I have an issue with my PrestaShop in version 1.7.7.8. When trying to create a new order in the Back Office (BO), I can log in and select a customer, but when it comes to choosing products for the cart, it keeps searching for products and doesn't display any results. I have products with combinations. It has always worked fine before. Additionally, when trying to add a product to an existing order, it also doesn't find any products.
Can you please help me? Thank you.
