Meaning

Look at WooCommerce → Status → Logs (fatal-errors and gateway logs). Cached checkout pages break nonces; gateway API keys, webhook config or currency settings cause payment failures.

Common causes

  • Payment gateway API error (keys, test/live mismatch, currency)
  • Cached checkout page with stale nonce
  • PHP fatal error in a checkout hook
  • Required field/validation from a plugin failing silently

⚡ Quick fix

  1. Check WooCommerce → Status → Logs
  2. Exclude checkout from caching
  3. Verify gateway keys/mode and webhooks

Detailed fix by platform

Shell

  1. php
    ls -t wp-content/uploads/wc-logs/ | head
wp wc tool run clear_transients --user=1

How to diagnose

  1. Logs — Gateway and fatal-errors logs
  2. Cache — Checkout cached?
  3. Gateway — Test/live keys
