WordPress monitoring
Your WordPress site updated. Did anything break?
A routine plugin or theme update can break your WordPress front end while the dashboard still says everything is fine. Sitewatch checks your site the way a visitor's browser does and alerts you the moment that happens — so you hear it from us, not from a customer.
- Catches plugin, theme and page-builder breakage after every auto-update
- Checks what visitors experience — not just whether the server answered
- No plugin to install, nothing to slow your site down. Live in two minutes
Homepage broke after a plugin update
Plain-English summary
A plugin update left a script conflict, so your navigation menu no longer opens. The server still answers normally.
01What can go wrong
One update. A dozen ways to break.
WordPress is a stack of moving parts — core, a theme, and a dozen plugins, each on its own update schedule, each able to change what your visitors load.
- 01A plugin auto-updates overnight and conflicts with your theme's scripts.
- 02The homepage still answers normally, so uptime tools stay green.
- 03But the navigation menu no longer opens, and the styling only half-loaded.
- 04Customers cannot use the site, and nobody on your team is watching the front end.
- Your uptime tool still says everything is healthy.
02Why traditional monitoring misses this
Your monitor says the site is healthy. It only checked one thing.
Traditional uptime monitoring stops the moment the server answers. We don't just check that your site is online — we check that people can actually use it.
Traditional uptime monitoring
Two steps. Everything after "it answers" is invisible.
Sitewatch
Only "healthy" once the whole page holds together.
03How Sitewatch catches it
One question, after every update.
Not "did the server respond?" — but the one your customers care about: can a visitor actually use the site?
- ✓The layout loads
- ✓Menu scripts load
- ✓Form scripts load
- ✓Images and thumbnails appear
- ✓Fonts load
- ✓Checkout pages still load
- ✓Certificate is valid
- ✓Content matches its baseline
04Typical failures we catch
The WordPress breakage visitors hit first.
Plugin update broke the theme styling
An update renames a file the cached page still points at.
→The page renders as raw text and visitors leave
Contact form stopped emailing
A form plugin update breaks the script the form depends on.
→Enquiries disappear and nobody notices for weeks
Main menu no longer opens
Two plugins clash and the navigation script errors.
→Visitors cannot reach anything but the homepage
White screen of death
A fatal error leaves a blank page — sometimes still answering normally.
→The site is gone for visitors while your monitor stays green
Page-builder widget vanished
An Elementor, Divi or Beaver Builder update drops one of its own files.
→Sections of the page render empty
WooCommerce checkout stopped working
An update conflicts with the theme and the cart script fails.
→Customers cannot complete a purchase
Certificate expired
A lapsed certificate is the most preventable outage there is.
→Browsers block the site with a full-page warning
Images and thumbnails missing
An image-optimisation plugin or media move leaves them unreachable.
→Product shots and featured images render blank
Permalink change created a redirect loop
A permalink or server-rule change sends visitors in circles.
→Visitors see "this page isn't working" and search rankings slip
05Beyond updates
The other ways WordPress sites fail
Real downtime and server errors
CriticalA crashed process, a database connection error, or an overloaded host takes the site fully offline. Sitewatch does the fundamental availability checks too, and confirms them before alerting.
The white screen of death
CriticalA plugin conflict or fatal error leaves a blank page — often while the server still reports success, which fools basic uptime checks. Sitewatch compares the rendered page against its baseline and flags the collapse.
Hacked or defaced pages
CriticalA compromised site usually injects unfamiliar scripts, swaps content, or redirects to spam domains. Sitewatch alerts on unexpected third-party scripts, content that drifts from its baseline, and new redirect destinations.
Security protections silently removed
ModerateA deploy or plugin change strips the headers that protect your visitors. The site still loads, but its protections are gone. Sitewatch tracks them and alerts the moment one disappears.
06A real example
A plugin update, caught before your customers call.
Update ships
A plugin auto-updates overnight.
Site breaks
A script conflict stops the menu opening.
Incident opened
Sitewatch confirms it is real and opens an incident.
You are alerted
Email or Slack, naming the file that broke.
Fixed
Before a customer ever calls.
07Setup in minutes
How to monitor a WordPress site
- 01
Add your WordPress URL
Paste your site URL — the homepage plus any page you cannot afford to lose, like checkout, login or a key landing page. No plugin, no server access.
- 02
Sitewatch recognises WordPress
It identifies WordPress, your theme, common plugins and your host or CDN, then tailors its checks and its fix guidance to that setup.
- 03
Choose how often and where
Every 30 minutes on Free, down to every 5 on Pro. Route alerts to email, Slack, webhook, PagerDuty, Opsgenie or SMS.
- 04
Connect a deploy hook (optional)
Add a webhook to your update workflow so a check runs the moment you update a plugin, theme or core — catching breakage in minutes rather than at the next interval.
08What happens the moment we find it
Detection is not the outcome. Getting it fixed is.
Every incident arrives already diagnosed, tailored to the WordPress stack we detected on your site.
We confirm it is real first
Every issue is re-checked before anyone is alerted, so a momentary hiccup during an update never wakes you at 3am.
Explained in plain English
"A plugin update left a script conflict, so your navigation menu no longer works." Something you can forward to whoever maintains the site.
Pointed at the likely cause
Because Sitewatch recognises your theme, plugins and host, the fix guidance names the layer that changed rather than describing a generic error.
You can verify the fix
Roll back the plugin, then run a check on demand and watch the incident close — before you tell the client it is sorted.
09The WordPress stack
Six layers. An uptime check only sees the first one.
A WordPress site is not one thing. Pick a layer to see how it fails and what Sitewatch notices when it does.
Extensions
Plugins
✕How it fails
Two plugins clash after an auto-update and a front-end script errors — menus, sliders, forms stop responding.
✓How Sitewatch detects it
Every script the page loads is checked. A file that is gone, or replaced with an error page, is named in the alert.
Host and PHP
InfrastructureHow it fails — The host is overloaded or PHP crashes, and the site returns an error or nothing at all.
How Sitewatch detects it — Availability checks catch hard outages, timeouts and server errors, and confirm them with a retry before alerting.
WordPress core
ApplicationHow it fails — A core update fails halfway, leaving a maintenance page or a fatal error behind.
How Sitewatch detects it — We compare the rendered page against its baseline, so a collapse to a blank or near-blank page raises an incident even when the server answers normally.
The theme
PresentationHow it fails — A theme update changes or drops the stylesheet, and the page renders unstyled.
How Sitewatch detects it — Every stylesheet and font the page references is fetched and verified, so a missing one is caught on the next check.
Plugins
ExtensionsHow it fails — Two plugins clash after an auto-update and a front-end script errors — menus, sliders, forms stop responding.
How Sitewatch detects it — Every script the page loads is checked. A file that is gone, or replaced with an error page, is named in the alert.
Media and assets
ContentHow it fails — An optimisation plugin or a media move leaves images and thumbnails unreachable.
How Sitewatch detects it — Images are verified alongside scripts and styles, so blank heroes and missing product shots surface immediately.
Forms and checkout
RevenueHow it fails — A form or WooCommerce update breaks the flow that actually makes you money, while the homepage looks perfect.
How Sitewatch detects it — Add checkout, cart and contact pages as critical pages and they are checked on their own schedule with their own alerts.

13The 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 schedule, each able to change the content, scripts and styling your visitors actually load. That is 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
- Files go missing. A plugin update renames or removes a script. Your page — or your caching layer — still points at the old address, which is no longer there. The form, slider or checkout that depended on it quietly stops working, and the server still answers normally.
- Caching and CDN drift. A caching plugin or CDN layer keeps serving an old file, or serves it as the wrong kind of file, after an update. Browsers refuse it silently. This is one of the most common — and least visible — causes of broken assets.
- Routing changes. A permalink or server-rule change introduces a redirect loop, or sends visitors to the wrong host. Every request still gets a response, so uptime checks pass while real people see "this page isn't working."
What WordPress monitoring should actually check
Opening the homepage every five minutes tells you the server is alive. It tells you nothing about whether a form plugin update broke your lead form, or a WooCommerce update broke your cart. Effective WordPress monitoring verifies the whole page a visitor receives: every script and stylesheet it references, the redirects it follows, the security headers it carries, and its content against a known-good baseline. When something changes, you want the exact file and the likely cause — not just "down."
How Sitewatch monitors WordPress without a plugin
Sitewatch checks your site the same way a browser does — from the outside — so there is nothing to install inside WordPress and no performance cost to your site. It recognises WordPress, your theme, common plugins and your host or CDN, then tailors its diagnosis to that stack. Pair it with deploy hooks to run a check the moment you push an update. 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.
14Questions
WordPress monitoring questions, answered
No. Sitewatch monitors your site from the outside, the way a visitor's browser does. There is nothing to install, nothing that can slow your site down, and nothing that goes offline when WordPress itself is struggling. Setup takes about a minute — paste your URL and go.
Yes. When an update renames or removes a file your page still points at, that file is no longer served — and the form, slider or checkout depending on it silently stops working. Sitewatch checks every script and stylesheet your pages load, so a missing one becomes an incident naming the exact file, even though WordPress still answers normally.
Yes. Because monitoring happens externally, it works with WP Engine, Kinsta, SiteGround, Cloudways, shared hosting and self-hosted WordPress alike. If your site loads in a browser, Sitewatch can monitor it.
Yes. Sitewatch verifies that your theme's stylesheets, fonts and scripts are actually being served. A theme update that drops or renames one of them shows up as a missing file on the affected pages, usually before anyone visits.
Yes. Page builders like Elementor, Divi and Beaver Builder load a lot of their own scripts and styling, which makes them especially prone to breakage after updates. Because Sitewatch verifies everything the page actually loads — not just the homepage content — it catches a builder file that has gone missing or is being served as an error page, whichever builder produced the page.
Yes. Add your cart and checkout as critical pages and they are checked on their own schedule with their own alerts, so if an update breaks the purchase flow you hear about it before customers cannot buy. See WooCommerce monitoring for the store-specific checks.
Yes. The white screen of death is usually a fatal error or plugin conflict that leaves a blank page — often while the server still reports success, which fools basic uptime checks. Sitewatch compares the rendered page against its baseline, so a sudden collapse to an empty page raises an incident regardless of what the server reported.
Sitewatch is not a malware scanner, but it surfaces the symptoms of a compromise from the outside: unfamiliar third-party scripts appearing on your pages, content drifting from its known-good baseline, new redirects to domains you do not control, and security headers that suddenly disappear. Catching those early — before Google flags you or visitors see spam — is often the difference between a quick cleanup and a blocklisted domain.
Checks run every 30 minutes on the free plan, every 15 on Starter and every 5 on Pro. Connect a deploy hook to your update workflow and the check runs the moment you click "Update", so you find out within minutes rather than at the next interval. Every issue is confirmed with a retry first, so what reaches you is real.
Yes, and that is the point. Sitewatch does the fundamental availability checks — outages, timeouts, server errors, certificate expiry — and then keeps going to verify the page actually works. You get classic uptime monitoring plus the checks that catch post-update breakage, in one tool.
Yes. Sitewatch runs multiple sites from a single dashboard — up to 25 on Starter and 100 on Pro — with independent checks, per-site alert routing and client-facing status pages. Agencies typically use a separate workspace per client to keep alerts and data isolated.
It depends on what you need to catch. Plugin-based tools like Jetpack or ManageWP run inside WordPress and are strong on updates and backups, but they can go offline with the site they live on. Ping-based tools like UptimeRobot or Pingdom confirm the server responded but miss page-level breakage. Sitewatch is built for the failure that follows an update — a missing file, a stale cache, a redirect loop, all of which return a perfectly normal response — and it runs externally, so it keeps working when WordPress does not.
No. Sitewatch focuses on whether the site works: what loads, the redirects, availability, certificates and content changes. It does not measure load time or Core Web Vitals. Pair it with PageSpeed Insights if speed is what you need.
