WooCommerce Monitoring & Troubleshooting Guides
Everything NorthDuty has written about WooCommerce stores that look fine but stop taking orders: how to diagnose a broken checkout, how to test it safely, and how to catch the next failure before customers do.
Start here
WooCommerce failures rarely take the whole site down. The homepage loads, uptime monitors stay green, and meanwhile the Place order button spins, Stripe rejects every card, or add to cart silently does nothing. These guides are organised around those failures.
If something is broken right now, start with the troubleshooting guides at the top. If you are setting up a store for a client or preparing for a sale, go to the testing and monitoring guides further down.

3
Test checkout before it matters
Follow the checkout testing guide before launches, plugin updates, and sale periods like Black Friday.
4
Catch the next failure automatically
Use the monitoring guide and the tools comparison to decide how to run a real checkout test on a schedule.

Compare ShopwardenFrequently Asked Questions
Answers to common questions about NorthDuty and website monitoring.
Why does WooCommerce checkout break without any error on the site?
Most checkout failures happen after the page loads: a payment gateway script fails, a plugin update changes the checkout block, a caching rule serves a stale nonce, or a webhook stops reaching the store. The page returns 200, so uptime checks stay green while orders stop.
How often should a WooCommerce checkout be tested?
Manually after every plugin, theme, or WooCommerce update and before any sale. Automatically, a real-browser checkout test every 5 to 15 minutes catches failures within the same hour instead of when customers complain.
