Shopify Checkout Not Working?
Checkout failures are critical because they prevent orders from completing. Every minute your checkout is broken, you are losing revenue. This issue often appears suddenly after an app installation, a theme update, or a change to checkout settings.
Common causes
- App conflicts modifying checkout scripts or cart data
- Payment gateway errors or misconfiguration
- Custom checkout scripts with JavaScript errors
- Cart data corruption or stale session data
- Theme updates breaking checkout button or flow
- Shopify Payments or third-party gateway not connected
Quick checks
- 01Test checkout with a simple, new product
- 02Disable recently installed or updated apps
- 03Verify your payment provider is connected and active
- 04Check the browser console for JavaScript errors
- 05Try checkout in an incognito window to rule out cache
When to get expert help
If the issue persists after completing these checks, deeper investigation is required. Complex issues often involve code-level conflicts that cannot be resolved without direct store access.
