Your WooCommerce Store Updated. Is Checkout Still Working?

Add your checkout and cart URLs as monitored pages in Sitewatch. On every check, Sitewatch loads each page over HTTP and validates every asset it references — cart-fragments JS, the payment gateway script, theme CSS, and images. If the payment script 404s, the checkout enters a redirect loop, or a required asset is served with the wrong MIME type, you get an incident naming the exact URL and status code. No WooCommerce plugin required.

Yes — when the cause is a broken or missing asset, which it usually is. WooCommerce powers the mini-cart through wc-cart-fragments.js. If a plugin conflict or caching layer breaks that script (404, timeout, or wrong content type), Sitewatch flags it on the next check, even though the product page still returns 200 OK. For a literal click-the-button-and-confirm-the-cart-updates test, pair it with transaction monitoring.

Sitewatch validates the JavaScript that gateways inject into your pages — Stripe, PayPal, Square, Mollie, and others. If a WooCommerce or gateway-plugin update changes the script path and the old reference 404s, or the gateway's CDN times out, the payment form never renders and Sitewatch catches it. It does not log into your gateway dashboard or read transaction declines — it monitors whether the gateway's front-end code actually loads on your checkout.

Sitewatch's core checks validate page and asset integrity on the pages you point it at, including checkout and cart — which catches the asset-level failures behind most "checkout won't 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 is fully external HTTP monitoring. It fetches your pages the way a browser does and validates every linked asset — no plugin to install, no server-side code, no performance hit on your store. Setup is paste-your-URL-and-go, and because nothing runs inside WordPress, monitoring keeps working even when your store itself is struggling.

Its core checks validate the assets needed for transactions — cart JS, payment scripts, checkout page integrity — rather than submitting orders. Because most checkout failures are asset-level (a missing script means the payment form never renders), this catches the bulk of revenue-killing breakage. For scripted test orders, add transaction monitoring.

On Pro, checks run as often as every 5 minutes; Free runs up to every 30 minutes. To catch breakage the instant it ships, connect a deploy hook so a full check runs the moment you finish a WooCommerce, plugin, or theme update — not hours later when sales analytics dip. A 2-of-3 retry confirms the failure before alerting so you don't get paged by a single transient blip.

Yes. It validates the JavaScript files any gateway injects — Stripe, PayPal, Square, Mollie, and others. If the gateway's JS fails to load (404, timeout, CDN failure), Sitewatch catches it regardless of which gateway you use.

Yes. Elementor, Divi, Beaver Builder, and other page builders generate additional JS and CSS that Sitewatch validates. Builders are especially prone to broken-asset issues after updates, and because Sitewatch checks every asset the page actually loads, a builder script that 404s gets flagged.

Yes. When a caching, security, or SSL plugin collides with a WooCommerce update and sends the checkout page into a redirect loop, an uptime tool follows the redirects and reports the site as up. Sitewatch detects the loop, flags it as an incident, and tells you which page is affected — 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 dynamic cart or checkout serves stale or empty carts, which is genuine breakage worth catching. Sitewatch's 2-of-3 retry filters out transient blips so a momentary CDN hiccup doesn't page you, while persistent stale-asset problems are surfaced with the exact URL.

WordPress monitoring covers general WordPress failures — plugin conflicts, theme breakage, cache issues. This page focuses on WooCommerce-specific commerce failures: cart fragments, payment gateways, checkout flows, and their direct revenue impact. Most stores want both, and a single Sitewatch site can check storefront and checkout pages together.

Sitewatch has 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. Asset validation, checkout-page checks, deploy hooks, and SSL and domain-expiry monitoring are included on every plan — the higher tiers add more sites and faster check intervals, which matters most for agencies managing many client stores.
