WooCommerce monitoring
Your store updated. Can customers still check out?
One plugin update can break the checkout while every page still loads fine — and the till just goes quiet. Sitewatch checks your cart and checkout the way a customer's browser does, and alerts you the moment the purchase flow breaks. You find out in minutes — not from a dip in tomorrow's orders.
- Cart, checkout and payment scripts checked on every run
- Catches the plugin and theme conflicts that follow every update
- No plugin to install and no impact on store speed
Checkout stopped accepting payments
Plain-English summary
The payment form's script is no longer being served, so the card fields never appear. The checkout page itself loads perfectly.
01What can go wrong
The storefront looks perfect. Nobody can buy.
Checkout is the most fragile page you own. It stitches together a cart script, a payment provider's code, your theme and a stack of plugins — and every one of them has to work.
- 01WooCommerce, your theme and three plugins all update in the same overnight batch.
- 02Product pages still look perfect, so nothing seems wrong.
- 03But the payment fields never appear, and "add to cart" leaves the cart empty.
- 04Customers try twice, assume the store is broken, and leave.
- You find out from tomorrow's order count.
02Why traditional monitoring misses this
Your monitor loaded the checkout page. That is not the same as checking out.
Traditional uptime monitoring stops the moment the server answers. We don't just check that your store is online — we check that people can actually use it.
Traditional uptime monitoring
The checkout URL loaded. Whether anyone could buy is invisible.
Sitewatch
Only "healthy" once the whole purchase path holds together.
03How Sitewatch catches it
One question, on every check.
Not "did the checkout URL respond?" — but the one your revenue depends on: could a customer actually complete this purchase?
- ✓The cart page loads
- ✓Mini-cart scripts load
- ✓Payment scripts load
- ✓Product images appear
- ✓Theme styling is intact
- ✓Checkout is reachable
- ✓No redirect traps
- ✓Certificate is valid
04Typical failures we catch
The store breakage that costs you orders.
Payment form never appears
An update changes where the gateway's script lives and the old address is dead.
→Customers reach checkout and cannot pay
Add to cart does nothing
The mini-cart script breaks, so the cart never updates.
→Shoppers assume the store is broken and leave
Checkout caught in a redirect loop
A security or caching plugin collides with an update — only on checkout.
→Every product page works and nobody can buy
A cached cart shows the wrong contents
A page cache captures the dynamic cart or checkout.
→Customers see empty carts or the wrong totals
Plugin conflict after a batch update
New versions clash and only cart, checkout or account pages error.
→The revenue pages fail while the catalogue looks fine
Product images missing
A media or CDN change leaves gallery and thumbnail images unreachable.
→The catalogue looks abandoned and nobody adds to cart
Certificate expired
A lapsed certificate on a store is the most expensive kind of outage.
→Browsers warn shoppers away from the payment page
Coupon or shipping calculator errors
A plugin update breaks the script the checkout extras depend on.
→Orders stall at the last step
A half-finished update
A large update times out partway and the storefront expects data that is not there.
→Product pages show errors or come up empty
05A real example
A dead payment form, caught before the day's orders are lost.
Update ships
A gateway plugin updates overnight.
Checkout breaks
The payment script is no longer where the page expects it.
Incident opened
Sitewatch confirms it is real and opens an incident.
You are alerted
Slack or email, naming checkout and the missing file.
Fixed
Before the morning's shoppers arrive.
06What happens the moment we find it
Detection is not the outcome. Getting orders flowing again is.
Every incident names the page and the file, so the fix starts immediately instead of with an investigation.
We confirm it is real first
Every issue is re-checked before you are alerted, so a momentary hiccup during an update never pages you at 3am.
Explained in plain English
"The payment form's script is missing, so the card fields never appear." Not a status code — a sentence you can hand to your developer.
Sent where your team already works
Slack, email, webhook, PagerDuty, Opsgenie or SMS, naming the affected page and the exact file.
You can verify the fix
Roll back the plugin, run a check on demand, and watch the incident close before you reopen the store to traffic.
07Inside a checkout check
What we see that a ping cannot.
The same page, two different answers
An uptime check asks the checkout page whether it exists, gets a yes, and stops. Sitewatch opens the page and then goes after everything it depends on — the cart script, the payment provider's code, the styling, the images. The checkout below answered perfectly. It also could not take a payment.
And what it looks like once it is fixed
Roll back the plugin, run a check on demand, and the incident closes on the evidence rather than on somebody's word that it should be fine now. That is the difference between reopening the store and hoping.
08Who it's for
Built for the people who lose money when checkout breaks.
Store owners →
Know your purchase path is working before the day's traffic arrives.
WordPress teams →
The store sits on WordPress, and so do most of the ways it breaks.
Agencies running client stores →
One dashboard, per-store alerts, client-facing status pages.
Teams running promotions →
Protect the landing and offer pages that feed the store at peak.
09Everything we detect
The full checklist on every store check
The purchase path
- Missing cart and mini-cart scripts
- Missing payment-gateway scripts — Stripe, PayPal, Square, Mollie and others
- Missing coupon, tax and shipping-calculator scripts
- Checkout, cart and account pages reachable and answering
- Redirect loops that affect only the checkout
The storefront
- Missing theme styling and fonts — the catalogue renders unstyled
- Missing product, gallery and thumbnail images

- Hard outages, timeouts and server errors
- Certificate expiry, with warning well before the date
- Unexpected content changes against your baseline

11The silent-failure problem
Why your checkout page looks healthy while customers cannot buy
A WooCommerce checkout is one of the most fragile pages on the web. It stitches together the cart's live updates, a payment provider's externally hosted code, your theme's styling, and often a stack of plugins — coupons, shipping calculators, tax engines — that all have to work for an order to complete. When any one of them fails, the server still builds the page and reports success. The customer sees a checkout form that will not submit, a payment field that never appears, or an "Add to cart" button that does nothing. Your uptime monitor sees a healthy site. (This is the failure people mean when they say a page loads but is broken.)
WooCommerce monitoring means verifying that the cart, checkout and payment path actually work — not just that the server responded. It is the difference between "the checkout page loaded" and "a customer could complete a purchase."
The failures that still look healthy
- Add to cart does nothing. WooCommerce updates the mini-cart in the background. A plugin conflict, or a caching layer that strips the response, leaves the button looking normal while the cart stays empty. See broken assets monitoring for how missing files get caught.
- The payment script is gone. A WooCommerce or gateway plugin update changes where the provider's code lives. The old address is dead, so the payment form never renders. The checkout page itself loads fine.
- Checkout redirect loop. A security or caching plugin collides with an update and sends checkout in circles. Every product page works; only checkout is unreachable.
- A stale cached cart. A page cache captures the dynamic cart or checkout, so customers see empty carts or another session's totals.
How Sitewatch monitors WooCommerce checkout
Sitewatch checks your store from the outside — the same way a browser loads it — so there is no plugin to install and no impact on store performance. Point it at your critical pages, including cart and checkout, and on every run it verifies each file those pages depend on: the cart's scripts, the payment provider's code, theme styling and images. A missing payment script or a checkout redirect loop becomes an incident naming the exact page and file, confirmed with a retry so a single blip never pages you. Wire up a deploy hook after WooCommerce updates and the check runs the moment you click "Update."
Verifying the page and everything it loads catches the large majority of "checkout looks fine but will not convert" failures, because most of them are a missing or broken file. For a scripted, multi-step purchase walkthrough — add to cart, fill the form, submit a test order — pair it with transaction monitoring and form monitoring. Running on a different platform or several stores? See Shopify monitoring, platform-agnostic e-commerce monitoring, or Sitewatch for agencies for multi-store dashboards and white-label client reports.
12Questions
WooCommerce monitoring questions, answered
Add your checkout and cart pages as monitored pages. On every run, Sitewatch opens each one and verifies everything it depends on — the cart's scripts, the payment provider's code, theme styling and images. If the payment script is gone, the checkout falls into a redirect loop, or a required file is served as the wrong kind of file, you get an incident naming the exact page and file. No WooCommerce plugin required.
Yes, when the cause is a broken or missing file — which it usually is. WooCommerce updates the mini-cart through a script that a plugin conflict or caching layer can easily break. If that script is missing, times out, or comes back as the wrong kind of file, Sitewatch flags it on the next check even though the product page looks perfectly healthy. For a literal click-the-button-and-confirm-the-cart-updates test, pair it with transaction monitoring.
Sitewatch verifies the code that gateways inject into your pages — Stripe, PayPal, Square, Mollie and others. If an update moves the script and the old address is dead, or the provider's network times out, the payment form never renders and Sitewatch catches it. It does not log into your gateway dashboard or read declined transactions; it checks whether the gateway's front-end code actually loads on your checkout.
Sitewatch's core checks verify the pages you point it at, including cart and checkout, and everything those pages load — which catches the failures behind most "checkout will not convert" incidents. For a scripted multi-step flow (add to cart, fill the form, submit a test order, confirm the thank-you page), use transaction monitoring and form monitoring alongside it.
No. Sitewatch monitors from the outside. It opens your pages the way a browser does and verifies everything they load — no plugin, no server-side code, no impact on store performance. Setup is paste-your-URL-and-go, and because nothing runs inside WordPress, monitoring keeps working even when your store is struggling.
No, and we would rather be clear about it. Its checks verify everything a transaction needs — cart scripts, payment code, checkout page integrity — rather than submitting an order. Because most checkout failures come down to a missing file, that catches the bulk of revenue-killing breakage. For scripted test orders, add transaction monitoring.
Checks run every 30 minutes on Free, every 15 on Starter and every 5 on Pro. To catch breakage the moment it ships, connect a deploy hook so a full check runs as soon as you finish a WooCommerce, plugin or theme update — rather than hours later when sales dip. Every issue is confirmed with a retry before alerting, so a single transient blip never pages you.
Yes. It verifies the files any gateway injects — Stripe, PayPal, Square, Mollie and others. If the gateway's code fails to load, whether because it moved, timed out, or its network is having a bad day, Sitewatch catches it regardless of which gateway you use.
Yes. Elementor, Divi, Beaver Builder and others generate a lot of their own scripts and styling, which Sitewatch verifies alongside everything else. Builders are especially prone to breakage after updates, and because Sitewatch checks everything the page actually loads, a builder file that has gone missing gets flagged.
Yes. When a caching, security or certificate plugin collides with an update and sends checkout in circles, an uptime tool follows the redirects and reports the store as up. Sitewatch detects the loop, raises an incident, and names the affected page — typically checkout, while the rest of the store works fine.
Caching is more often the cause of real failures than of false alerts — a page cache that captures the live cart or checkout serves stale or empty carts, which is genuine breakage worth catching. Every issue is confirmed with a retry, so a momentary CDN hiccup does not page you, while a persistent stale-file problem is surfaced with the exact address.
WordPress monitoring covers the general failures — plugin conflicts, theme breakage, cache problems, the white screen. This page focuses on the commerce path: cart, payment, checkout and the revenue they carry. Most stores want both, and a single Sitewatch site can check the storefront and the checkout together.
There is a free plan for 1 site, Starter at $9/month for up to 25 sites, and Pro at $19/month for up to 100 sites. Checkout-page checks, deploy hooks, and certificate and domain-expiry monitoring are included on every plan — the paid tiers add more sites and faster check intervals, which matters most for agencies running many client stores.
