IT doesn't works.....blank page...and the categories doesn't shows on settings page. Thank you
The Commerce module works well, but you have to follow step vy step the support article to set up this feature.
Usually, your issue is due to the fact you haven't added a tax, or you don't add a tax to a product, , or you didn't set up Paypal well if you use Paypal, or you didn't create categories (the root category is never displayed, just add other sub-categories and link your products to one subcategory at least), etc.
Here is the support article:
