Can’t see product bundle on single product page

Hi,

I’ve installed the free version of the plugin, I’ve created a product bundle and I’ve added on it some bundle following this guide https://www.asanaplugins.com/woocommerce-product-bundles-free-plugin/

Now, if i go to the product page, and clic on select a product, all i get is a blank popup.

If i set the “use default product” option, I can’t see the product information on single product page, but i can add it in cart, and in cart page I can see the product informations.

I’ve tried to disable all plugins and theme, but I still have the problem

Can you pls help?
