Shopify Add to Cart Not Working: Causes and How to Fix It

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.

2. Theme Conflicts

Custom code or recently installed apps may interfere.

3. AJAX Cart Issues

Many themes use AJAX for cart updates.

4. Product Availability

Products that are sold out or unpublished can’t be added.

5. Third-Party Apps

Upsell, bundle, or subscription apps sometimes override cart behavior.

Step-by-Step Fixes

  • Check browser console

  • Disable recently installed apps
  • Verify product variants
  • Update theme files
  • Clear browser cache

When to Hire a Shopify Developer
