Products appear as not available

Hi!

I have few products with 3 atributes (color, size, male/female) and I have deactivated the stock administration option in Woocomerce/Settings/Products/Stock.
When I try to add a product in the cart, I receive the message: “We are sorry, this product is not available. Please try a different combination”. No matter what combination of the 3 variables I try, the message is the same.
The same message appear also if I activate the stock administration option and I insert a relatively big enough number of units in stock (1000).

Please help! I use Woocommerce 3.4.2 and Word Press 4.9.6–ro_RO

Thanks,
Andreea
