Troubleshooting - WooCommerce Checkout Not Working: Troubleshooting Guide
Fix WooCommerce checkout problems. Troubleshoot payment failures, shipping errors, and checkout page issues step by step.
The Problem
Checkout problems directly cost you sales. Every broken checkout is a customer who wanted to buy but couldn't.
The Solution
We systematically diagnose checkout issues-from page configuration to payment gateway to plugin conflicts.
Page Configuration
WooCommerce needs specific pages properly configured. Missing or wrong pages break checkout.
- Verify checkout page in WooCommerce > Settings > Advanced
- Check that checkout page contains [woocommerce_checkout] shortcode
- Ensure cart page is also correctly set
- Clear all caches after page changes
- Test with permalinks refreshed (save permalink settings)
Payment Gateway Issues
Payment problems are the most common checkout failure. Gateway configuration must be exact.
- Verify API keys are correct (live vs test)
- Check SSL certificate is valid and active
- Enable payment gateway logging to see errors
- Test with a different payment method
- Check for gateway plugin updates
JavaScript Conflicts
Checkout relies heavily on JavaScript. Conflicts cause buttons that don't work and validation that fails.
- Check browser console for JavaScript errors
- Test with all plugins except WooCommerce disabled
- Try a different browser to rule out extensions
- Disable minification/optimization temporarily
- Check for jQuery conflicts
Shipping Configuration
Shipping errors can prevent checkout from completing, especially "no shipping methods available."
- Verify shipping zones cover customer locations
- Check shipping method is enabled for zone
- Test with flat rate shipping to isolate issue
- Verify product shipping settings (weight, dimensions)
- Check shipping class configuration

Start with these high-impact, low-effort improvements.
- 1 Clear all caches and test again
- 2 Check WooCommerce > Status for system errors
- 3 Enable gateway debug logging
- 4 Test checkout as guest user in incognito

FAQ - Common questions
Answers to questions we often hear about this topic.
Checkout worked yesterday. What changed?
Check for recent plugin or theme updates. Review WooCommerce > Status > Logs for errors. Check if your payment gateway had an outage. Sometimes SSL certificates expire causing payment failures.
Orders are created but payment fails.
This usually indicates the payment gateway is rejecting the transaction. Check gateway logs, verify API credentials, and ensure your merchant account is in good standing.
