WordPress monitoring

Your WordPress Site Updated. Did Anything Break?

WordPress sites fail in more ways than "down." The server goes offline, a plugin update renames a script, a bad deploy triggers the white screen of death, or an injected script signals a hack — all while a basic uptime ping stays green. Sitewatch monitors WordPress uptime and every asset, header, and redirect on the page, auto-detects your stack, and tells you what broke and how to fix it.

  • Uptime + full page-integrity checks on every cycle
  • Catch plugin, theme, and update breakage automatically
  • Security-header and content-change alerts flag hacks early

WordPress-specific failures

The silent breakage that follows every update

Plugin update breaks JS

Critical

A Contact Form 7 update renames a script file. The old reference in your cached page returns a 404. The form looks normal but never submits. Your uptime tool sees nothing wrong.

Theme update breaks CSS

Critical

A theme update changes the stylesheet structure. Your caching plugin still serves the old CSS. Visitors see a broken layout while your server happily returns 200 OK.

Permalink redirect loop

Critical

A permalink structure change combined with an .htaccess misconfiguration creates a redirect loop. The server responds to every request. Real visitors see "this page isn't working."

Caching plugin serves stale assets

Moderate

WP Super Cache, W3 Total Cache, or LiteSpeed Cache serves an old version of a JS file that no longer exists at the referenced URL. The CDN returns a 404 or the wrong content.

Image optimization failure

Moderate

ShortPixel, Imagify, or Smush processes images that end up broken or inaccessible. Product images disappear. Featured images fail to load.

WooCommerce cart breakage

Critical

A WooCommerce update conflicts with a custom theme or plugin. The cart JS bundle fails to load. Add-to-cart buttons stop working. Revenue drops while the checkout page still "loads."

Beyond updates

The other ways WordPress sites fail

Downtime and 5xx errors

Critical

A PHP-FPM crash, a database connection error ("Error establishing a database connection"), or an overloaded host takes the site fully offline. Sitewatch's uptime checks catch real downtime and 5xx responses and alert you immediately.

White screen of death

Critical

A plugin conflict or PHP fatal error leaves a blank white page — no content, no error, sometimes still a 200. Sitewatch fingerprints the rendered page and flags the sudden collapse so you catch the WSOD before visitors do.

Hacked or defaced pages

Critical

A compromised WordPress site often injects unknown scripts, swaps content, or redirects to spam domains. Sitewatch alerts on unexpected third-party scripts, content changes against your baseline, and new redirect destinations.

Security-header regressions

Moderate

A deploy or plugin change silently strips CSP, HSTS, or X-Frame-Options. The site still loads, but its protections are gone. Sitewatch tracks security headers and alerts the moment one disappears.

Built for WordPress

WordPress-aware monitoring that catches what uptime tools miss

Automatic WordPress detection

Sitewatch auto-detects WordPress, your theme framework, active plugins, and hosting environment. Root cause diagnosis and fix playbooks are tailored to your exact setup.

Every asset validated

Scripts, stylesheets, fonts, and images referenced in your pages are checked for HTTP status and MIME type on every monitoring cycle. A 404'd plugin script gets caught immediately.

Post-update verification

Deploy hooks trigger an instant website check after updates. Catch the broken Contact Form 7 script or missing WooCommerce asset within minutes of updating.

Multi-site management

Agencies managing 20, 50, or 100 WordPress client sites get one dashboard with per-site alerts, per-client status pages, and deploy hooks for each environment.

The WordPress update problem

Why WordPress sites break after updates — and uptime tools stay green

WordPress runs roughly 40% of the web, and almost none of those sites are static. Every WordPress site is a moving stack of core, a theme, and a dozen or more plugins — each on its own update cadence, each capable of changing the HTML, scripts, and styles your visitors actually load. That's what makes WordPress monitoring different from plain uptime monitoring: the server can be perfectly healthy while the page is broken.

The three ways an update silently breaks a WordPress site

  • Asset references go stale. A plugin update renames or removes a JavaScript file. Your page (or your caching layer) still points at the old URL, which now returns a 404. The form, slider, or checkout that depended on it quietly stops working — and the server still returns 200 OK.
  • Caching and CDN drift. WP Super Cache, W3 Total Cache, LiteSpeed, or a Cloudflare layer serves a stale asset or the wrong MIME type after an update. Browsers reject it silently. This is one of the most common — and least visible — causes of broken assets.
  • Routing and permalink changes. A permalink or .htaccess change introduces a redirect loop or sends visitors to the wrong host. Every request still gets a response, so uptime checks pass while real users see "this page isn't working."

What WordPress monitoring should actually check

Pinging the homepage every five minutes tells you the server is alive. It tells you nothing about whether a Contact Form 7 update broke your lead form or a WooCommerce update broke your cart. Effective WordPress monitoring validates the full rendered page: every linked script and stylesheet's HTTP status and content type, the redirect chain, security headers, and the page's structure against a known-good baseline. When something changes, you want the specific asset URL and the likely cause — not just "down."

How Sitewatch monitors WordPress without a plugin

Sitewatch checks your site the same way a browser does — externally, over HTTP — so there's nothing to install inside WordPress and zero performance impact on your site. It auto-detects WordPress, your theme, popular plugins, and your host/CDN, then tailors its root-cause diagnosis to that stack. Pair it with deploy hooks to run an instant check the moment you push an update, and if you manage many sites, see Sitewatch for agencies for multi-site dashboards and white-label client reports. Running a store? WooCommerce monitoring adds cart- and checkout-specific checks.

Setup in minutes

How to monitor a WordPress site

01

Add your WordPress URL

Paste your site URL into Sitewatch — homepage plus any critical pages like checkout, login, or a key landing page. No plugin to install, no server access needed.

02

Sitewatch auto-detects WordPress

It identifies WordPress core, your theme, popular plugins, and your host/CDN, then tailors checks and fix guidance to that stack automatically.

03

Set check frequency and alerts

Choose an interval (every 30 minutes on Free, down to 5 minutes on Pro) and route alerts to email, Slack, or webhooks. Uptime and full page-integrity checks both run on every cycle.

04

Connect a deploy hook (optional)

Add a webhook to your update or deploy workflow so Sitewatch runs an instant check the moment you update a plugin, theme, or core — catching breakage in minutes.
