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
CriticalA 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
CriticalA 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
CriticalA 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
ModerateWP 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
ModerateShortPixel, Imagify, or Smush processes images that end up broken or inaccessible. Product images disappear. Featured images fail to load.
WooCommerce cart breakage
CriticalA 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
CriticalA 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
CriticalA 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
CriticalA 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
ModerateA 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.

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
.htaccesschange 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
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.
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.
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.
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.
WordPress monitoring FAQ
Yes. Sitewatch monitors externally over HTTP — no server-side plugin needed. It works with WP Engine, Kinsta, SiteGround, Cloudways, shared hosting, and self-hosted WordPress. If your site loads in a browser, Sitewatch can monitor it.
The best WordPress monitoring tool depends on what you need to catch. Plugin-based tools (like Jetpack or ManageWP) run inside WordPress and report on updates and uptime, but they can go down with the site they live on. External tools like UptimeRobot ping the server but miss page-level breakage. Sitewatch is built for the failure mode that matters most after updates — broken assets, stale caches, and redirect loops that return 200 OK — and it runs externally with no plugin, so it keeps working even when WordPress itself is struggling.
Yes. Sitewatch runs lightweight ping checks for uptime tracking and full integrity checks that validate every asset on the page — both on every monitored site. You get classic uptime monitoring plus the page-level checks that catch post-update breakage, in one tool.
Sitewatch analyzes your page HTML and HTTP response headers during every check. It identifies WordPress core, your theme framework, popular plugins (WooCommerce, Contact Form 7, Elementor, etc.), and your hosting/CDN environment. This detection powers stack-specific fix playbooks.
Yes. When a plugin update changes or removes a script file, the old reference in your cached page returns a 404. Sitewatch checks every linked script and stylesheet on your pages. A missing or broken asset triggers an incident with the exact URL and HTTP status code.
No. Sitewatch is fully external. It fetches your pages over HTTP and validates every linked asset. No plugins, no server-side code, no performance impact. Setup takes about 60 seconds — paste your URL and go.
Yes. Sitewatch supports monitoring multiple sites from a single dashboard. The Pro plan covers up to 100 sites at $19/month. Each site gets independent checks, per-site alert routing, and a client-facing status page.
Check intervals are configurable per site — from every 30 minutes on Free up to every 5 minutes on Pro. You can also trigger on-demand checks after updates using the dashboard or deploy hooks.
The reliable way is to compare the page after the update against a known-good baseline. Sitewatch fingerprints your page HTML and validates every linked asset on each check, so when an update changes or removes a script, breaks a stylesheet, or alters the redirect chain, you get an incident naming the exact asset and HTTP status — usually within minutes of the update, not when a visitor complains. Connect a deploy hook and the check runs the moment you click "Update."
Yes. Page builders like Elementor, Divi, and Beaver Builder load a lot of their own scripts and stylesheets, which makes them especially prone to broken-asset issues after updates. Because Sitewatch validates every asset the page actually loads — not just the homepage HTML — it catches a builder script that 404s or a stylesheet served with the wrong MIME type, regardless of which builder produced the page.
Sitewatch is not a malware scanner, but it surfaces the symptoms of a compromise from the outside: unexpected third-party scripts appearing on your pages, content that changes against your known-good baseline, new redirects to unfamiliar domains, and security headers that suddenly disappear. Those are common signs of a hacked WordPress site, and catching them early — before Google flags you or visitors see spam — is often the difference between a quick cleanup and a blocklisted domain.
Yes. The white screen of death (WSOD) is usually a PHP fatal error or plugin conflict that leaves a blank page — sometimes still returning a 200 status, which fools basic uptime checks. Sitewatch fingerprints the rendered page, so a sudden collapse to an empty or near-empty page triggers an incident even when the HTTP status looks fine — so you find out the moment the site goes blank, not when a visitor reports it.
Plugin-based tools (Jetpack, ManageWP) run inside WordPress and are great for updates and backups, but they can go down with the site they live on. Ping-based tools (UptimeRobot, Pingdom) confirm the server responds but miss page-level breakage. Sitewatch combines external uptime checks with full page-integrity validation — assets, headers, redirects, and content — so it catches both downtime and the silent "up but broken" failures that plugin and ping tools miss.
