Why is the product not being added to the cart from the product card in shopkeeper?

Question

CMS

Hi, I installed the shopkeeper demo, at first everything was fine, then I noticed that from the product card, the product is not added to the cart, although everything is added from the category well. When you click on the add button, it asks how many pieces to add, then you press ok and the animation of adding to the cart occurs, but nothing is added. There are no errors in the console. Html button code

<div class="product-price">
    <button class="btn btn-lg btn-primary" type="submit">В корзину</button>
</div>

Answer 1

Issue resolved, just accidentally pulled the button out of the form

Answer 2

Here html code is not limited)
It is desirable to link to the site.
