Introduction
Few issues are more frustrating than customers clicking the Add to Cart button and nothing happens. This problem can lead to abandoned carts and lost sales.
In this guide, we’ll cover the most common causes and provide practical solutions to get your Shopify store working again.
Common Causes
1. JavaScript Errors
Broken JavaScript often prevents cart functionality.

Custom code or recently installed apps may interfere.
3. AJAX Cart Issues
Many themes use AJAX for cart updates.

Products that are sold out or unpublished can’t be added.
