Free basic custom stores are created with Sellvia Platform. It is not compatible with WooCommerce. So, if you have a free basic custom store, you shouldn't install WooCommerce on your site.
As per WooCommerce compatible plugins and add-ons (such as WooCommerce Stripe Payment Gateway, Facebook for WooCommerce, etc.), they should not be installed as well, because they will not work properly without WooCommerce.
So, if you want to have a store with WooCommerce, you should choose another option from AliDropship Custom Stores with pre-imported products.
