Why does the add to cart button hang on the bitrix site?

Question

1C-Bitrix

All ajax buttons of the online store "add to cart" after clicking on them hang with the text "add". Endless loading. What is in the teasers of the goods, what is in the product cards is the same.




However, after refreshing the page, items still appear in the cart.

Console throws an error

Cannot add to cart

What can be wrong?

Answer 1

Game, in the component settings in the "AJAX mode control" column, the "Enable AJAX mode:" checkbox was not set.

Answer 2

1. Check if the request is leaving (F12, Network tab);
2. Check the correctness of the request and response;
3. Check the file itself where the console is pointed to (check where the data comes from, whether they are filled, etc.)
Try to dig at least a little further than the console and everything will be fine;)
