Not able to order out of stock products

[bonsaiko]

Hello,

 

I have products with different colors. 

For one particular color, I added some quantity in stock, but not for others: 

I'm able to order products of this color, but not of the other colors. 

I already went into product detail, I and checked "available to order", and also into preferences / allow out of stock order.

 

In spite of all that, it's not working. 

Anyone could help me please ?

 

Thanks a lot.

I found the answer. For those who are in my case:

Got to the product details in the admin, and click on the quantity tab. Then scroll until you see "in case of out of stock" and check "accept orders". 

The labels may not be exactly as I say as my prestashop is in french so I just translated.
