Fulfillment not working

Hi,

I have a problem with orders by ALD plugin.

When I click on button “Order with Extension” It is opening new page with aliexpress. Then it is going to Product page and I see 2 notices, then It is going to cart page and nothing else. I was checking in my account orders at aliexpress and it is nothing beyond new shipping adress.

When I click on button “Aliexpress sync” It is opening new page with aliexpress orders. Then I’m getting notify “Finish syncing orders” with 0 orders.

When I click on button “Bulk place order” It is opening modal with product list and then notify “Invalid order items or system error”.

Please tell me what i’m doing in wrong way.
