Orders stopped, payments failing or the checkout page will not load? Here are the most common causes of Shopify and WooCommerce checkout problems and how to fix them fast.

Quick answer: Checkout failures usually come from a payment gateway issue (wrong API keys, expired credentials or failed webhooks), a plugin or app conflict, a theme customization that broke checkout scripts, caching on checkout pages, or shipping and tax rules that block the order. Place a test order, check the gateway dashboard and browser console, and disable recent changes one by one. QuickHire e-commerce support fixes checkout issues by the hour.
Checkout is the one page where every bug costs money directly. Even a small error can silently block orders for days before anyone notices.
Why is my WooCommerce checkout not working?
Plugin conflicts: a recently updated plugin breaks checkout scripts or AJAX calls.
Caching: cart and checkout pages are cached, so sessions and nonces fail.
Payment gateway settings: test mode left on, wrong keys or an expired webhook secret.
Theme overrides: outdated checkout template files in the theme.
Server limits: PHP errors, memory limits or a blocked REST API.
Why is my Shopify checkout not working?
Shopify hosts checkout itself, so issues usually come from around it:
A payment provider that is not fully activated or verified.
Apps that modify cart or checkout behaviour and conflict with each other.
Custom theme code on the cart page that breaks the redirect to checkout.
Shipping zones or rates that do not cover the customer's address.
Discount or market settings that block certain countries or currencies.
How to diagnose a checkout problem step by step
Place a test order as a guest on desktop and mobile, with a real-looking address.
Open the browser console on the checkout page and note any red errors.
Check the payment gateway dashboard for declined or failed API requests and webhook errors.
Review recent changes: plugin or app updates, theme edits and new discount rules.
Disable changes one at a time on a staging copy until checkout works.
Check orders stuck in pending to see if payments succeed but orders do not update.
Why are payments successful but orders stay pending?
This usually means the payment gateway cannot reach your store to confirm payment. Webhooks are failing because of a wrong URL, an expired secret, a firewall or a security plugin blocking the request. Fixing the webhook and re-syncing affected orders resolves it.

"There are no shipping options available" | Shipping zones or rates do not match the address |
Card declined for every customer | Gateway in test mode or wrong live keys |
Orders pending after payment | Failed webhooks between gateway and store |
Cart empties at checkout | Caching or session cookie issues |

Frequently asked questions
Why is my WooCommerce checkout page not loading?
The most common causes are a plugin conflict, caching on the checkout page, a JavaScript error from the theme, or a blocked AJAX or REST API request. Check the browser console and disable recent changes on a staging copy.
Why does Shopify say there are no shipping options available?
Your shipping zones or rates do not cover the customer's address, product weight or cart value. Review shipping profiles and make sure every market you sell to has a rate.
Why are orders stuck in pending payment?
Usually the payment gateway's webhook cannot reach your store to confirm payment. Check the webhook URL and secret, and make sure no firewall or security plugin is blocking it.
Can a plugin update break WooCommerce checkout?
Yes. Plugin and theme updates are among the most common causes of checkout failures. Test updates on staging and keep a backup so you can roll back quickly.
