Ajax add to cart button not working?

Question

WordPress

Hello.
Help solve the problem.
After installing the Popup Cart Lite for WooCommerce plugin, the Add to Cart button stopped working. Removing this plugin did not solve the problem.
When you click on the "Add to Cart" button, nothing happens or the store page simply reloads.
