Ecommerce troubleshooting
When WooCommerce checkout stops working, the symptom matters more than the first guess. A stuck place order button is different from an empty-cart redirect. A payment gateway error is different from a shipping-zone issue. A successful order with missing GA4 revenue is a tracking problem, not necessarily a checkout problem.
The useful first pass is to test the whole checkout path: product page, add to cart, cart, checkout fields, shipping, tax, payment method, order creation, thank-you page, email notifications, and purchase tracking. Each step narrows the issue before production changes make the store harder to debug.
Name the checkout symptom
WooCommerce checkout can fail in several ways. The page may reload without creating an order. The pay button may spin forever. A gateway may return a vague error. Shipping or tax may never calculate. The cart may empty after redirect. The order may complete while tracking fails.
Those symptoms point to different technical layers, so do not start by disabling random plugins in production.
Checkout symptoms to document
- Place order button spins or does nothing
- Checkout redirects to an empty cart
- Payment gateway error appears
- Shipping, tax, coupon, or address validation blocks checkout
- Checkout fields do not update or validate
- Order is created but purchase tracking is missing
- Only mobile or one browser fails
Check recent changes
Many checkout problems follow a recent update. WooCommerce, payment gateways, checkout field editors, shipping plugins, tax plugins, cache plugins, security plugins, optimization plugins, and themes can all change checkout behavior.
A short change log is often more useful than another generic troubleshooting list.
Recent changes worth checking
- WooCommerce or WordPress update
- Payment gateway update
- Theme or checkout template update
- Cache or optimization setting change
- Security, CAPTCHA, or firewall change
- Shipping, tax, or coupon plugin change
- Tracking script or GTM container update
Look for script, cache, and session issues
Checkout pages rely on JavaScript, AJAX requests, cookies, sessions, and payment gateway scripts. Caching or minification that is fine on a blog post can break checkout.
Browser console errors, failed network requests, stale checkout assets, blocked scripts, and cache exclusions usually reveal whether the problem lives in the browser, plugin stack, or server.
Technical checks
- Browser console errors
- Failed AJAX requests
- Checkout and cart pages excluded from cache
- Payment scripts loading correctly
- Security plugin or CAPTCHA blocking checkout
- Session/cookie behavior
- Optimization plugin script exclusions
Verify order data and tracking after the fix
A checkout fix is incomplete if orders work but reporting is broken. After checkout behavior is stable, check whether GA4, GTM, pixels, transaction IDs, revenue, currency, and item data match the WooCommerce order.
This matters because ecommerce decisions get worse when revenue reports drift away from real orders.
Post-fix verification
- Order created once
- Customer and admin notifications work
- Thank-you page loads
- GA4 purchase event fires once
- Transaction ID is present
- Revenue and currency match
- Product data is complete enough for reporting
