Shopify Checkout Not Working? Here’s How to Diagnose & Fix It (2025 Edition)
Introduction:
Is your Shopify checkout page suddenly not working or showing errors?
This can instantly kill sales — especially when customers are ready to pay.
Whether it's a loading issue, payment failure, or a blank screen, Shopify checkout problems are urgent and costly.
In this guide, we’ll walk you through common checkout issues in Shopify, why they happen, and how to fix them step-by-step (even if you're not a developer).
1. Common Shopify Checkout Errors in 2025
Here are the most frequent complaints store owners report:
| Issue Type | Description |
|---|---|
| 🛑 Checkout button not responding | Nothing happens when clicked |
| 🕳️ Blank or white screen | Checkout loads with no content |
| ❌ Payment method not working | Cards, UPI, or gateways fail to load or throw errors |
| 🌍 Location blocked at checkout | Certain countries can’t proceed with checkout |
| 📱 Mobile checkout broken | Elements overlap, don’t scroll, or crash |
| 🔄 Endless loading | Checkout freezes on loading spinner |
Let’s fix them one by one.
2. First: Check Shopify Status
Before diving deep, go to:

If there’s a Shopify-wide outage, your checkout will be affected temporarily. Wait it out — nothing to fix on your end.
3. Test Your Theme & App Conflicts
Custom themes and apps can break checkout functionality.
✅ Steps:
-
Go to Online Store > Themes > Customize > Actions > Preview your store with a default theme (e.g., Dawn)
-
Try the checkout flow again
If it works fine, the issue lies in:
-
Your theme’s custom code
-
An app injecting scripts into your cart or checkout page
🧩 Fix:
Disable recently added apps and test one by one.
4. Review Payment Gateway Setup
Go to:
Settings > Payments
🔍 Check:
-
Is your gateway (Razorpay, Stripe, etc.) properly connected?
-
Are there any errors or expired API credentials?
💡 Re-authenticate your payment provider if needed.
5. Check Checkout Settings & Restrictions
Navigate to:
Settings > Checkout
Look for:
-
⚠️ Customer account requirements (try setting to "optional")
-
🚫 Shipping restrictions by country or postcode
-
❓ Custom fields or scripts causing logic errors
📌 Tip: Avoid too many custom checkout scripts unless you're on Shopify Plus.
6. Clear Cache and Try Incognito Mode
Sometimes your browser is the issue — especially if you use ad blockers or browser extensions.
🧪 Try checkout in:
-
Chrome Incognito
-
Safari/Firefox
-
A mobile device
If it works here, ask your developer to test JS console errors in your normal browser.
7. Fix Mobile-Only Checkout Bugs
Over 70% of users shop on mobile — so if mobile checkout is broken, you’re losing real money.
📲 Test for:
-
Button overlap
-
Sticky headers covering content
-
Forms not autofilling
🛠️ Ask your developer to use Chrome Developer Tools > Device Mode to debug issues on mobile screens.
8. Enable Dynamic Checkout Buttons Properly
Dynamic checkout (Apple Pay, GPay) can fail if:
-
You haven’t configured them fully in payment settings
-
You’ve removed key product form code (e.g.,
form action="{{ routes.cart_add_url }}")
💡 Use Shopify documentation or a developer to reintegrate missing code.
9. Use Shopify Support (and Logs)
Still can’t find the issue?
🛠️ Go to:
-
Shopify Admin > Support > Contact Us
-
Provide a checkout link + screenshot + error description
Also, check:
-
Abandoned checkouts under Orders → This may reveal where users stopped
-
Use Shopify Flow (for Plus) to log checkout behavior
10. Prevent Future Checkout Issues
-
✅ Use a staging environment before installing new apps
-
🛡️ Avoid editing checkout.liquid unless you’re on Shopify Plus
-
🔄 Regularly test checkout after app/theme updates
-
📦 Use third-party checkout tools only if absolutely necessary
