“Add to cart” button is not working

Hi, I need your help with the issue that I have on the website which was created by some other person (this person disappeared) and now I’ve installed WooCommerce there and trying to make it work. That person created his own theme for this website so the issue is connected to that.

The problem is that “Add to cart” button is not working on the product page (meaning – when you click on the button nothing is happening). It works at the archive page but not in the product itself. When I’m changing the theme to TwentyNineteen for example – everything is perfect. I tried to find the issue in the theme but failed, I don’t see the problem.

Please please help me, what can cause this problem?
Link on one of the products: [ redundant link removed ]

P.S. The website is in Russian but it shouldn’t be a problem, add to cart button is “В корзину”.

Best regards,
Olga
