WP Health Inspector reads your PHP error log, traces each error back to the plugin that caused it, and tells you exactly which recent update triggered it — all without touching a single row of your data.
Ten core diagnostic modules plus eleven Pro-exclusive deep inspections — including Root Cause Analysis, Pre-Update Impact Analysis, and Plugin Conflict Detection. One health score. Zero risk. Built for agencies, developers, and site owners who need real answers, fast.
It reads your PHP error log, maps errors to the plugin or file that caused it, and correlates each one against your recent update history — so you know exactly what broke, when it broke, and which plugin, file, or change is responsible. All before you touch anything.
Fixing problems you don't understand is risky. This plugin makes those risks visible.
Most WordPress problems don't appear overnight. They accumulate silently — until something breaks.
A top-level 0–100 score that grades your site across its most impactful performance and safety dimensions — refreshed on demand via AJAX.
The dashboard analyses your live error log, autoload size, cron status, and pending updates — then surfaces the fastest routes to your current problem.
Most developers never read their error log. WP Health Inspector reads it for you — groups every PHP error by severity and frequency, and gives you a structured "Error Map" for each one: plain-English explanation, the probable cause extracted from the actual function or class that failed, numbered fix steps, and ready-to-run WP-CLI commands.
"Something broke after an update" is the most common WordPress support request — and the hardest to answer without this. What Changed? tracks every plugin update, activation, and WordPress core update as a timestamped event, then correlates them with your PHP error spikes to show exactly what broke your site and when.
Read-only queries that surface potential database bottlenecks without modifying a single row.
Maps every custom table, cron job, and REST route on your site — and attributes each one to the specific plugin that created it.
Inspects every script and stylesheet WordPress has enqueued on the front end — with file-level size data.
Understand what WordPress background tasks are actually doing — and which ones aren't running at all.
Every autoloaded option loads into PHP memory on every single page request. This module names the culprits and gives you the exact WP-CLI commands to clean them up.
Pre-flight compatibility checks for WordPress core upgrades — surface breaking changes before they break production.
Proactive alerts for things that will break your site in the near future — surfaced before they become emergencies.
A complete technical profile of your hosting environment — surfaced directly inside WordPress admin.
Three read-only security inspections that surface privilege creep, tampered plugin files, and exposed REST endpoints — before an attacker finds them.
Inspects your media library and permalink layer for orphaned files, broken references, and stale rewrite rules that quietly degrade user experience.
Server-side proxy estimates for LCP, CLS, and INP — correlated with detected performance issues so you know what to fix first.
Captures per-request execution time, peak memory, database query counts, and hook timelines — the data you need to pinpoint exactly where slowdowns originate.
The answer to "why is this site broken?" — without spending an hour opening twelve different screens. Root Cause Analysis cross-correlates your error log, slow queries, cron backlog, autoload bloat, and external dependencies into named, actionable findings — then tells you which plugin is responsible.
Shows exactly which plugins are fighting over hooks, loading duplicate assets, and providing overlapping functionality — with full plugin names, versions, and one-click deactivation links.
Tracks every outbound HTTP request your WordPress site makes — because a slow or failing third-party API can silently cripple your page load times.
Rolling snapshots of execution time, memory usage, and query counts over time — so you catch regressions the moment they start, not after clients report slowdowns.
Before you click "Update", know exactly what could break. Pre-Update Impact Analysis scores every pending plugin update with a 0–100 Blast Radius Score — weighted by shared hooks, custom database tables, cron jobs, REST routes, asset size, and error history — so you update with confidence, not hope.
Generate a comprehensive HTML diagnostic report from all available modules and hand it to a client, a colleague, or a hosting provider — without sharing credentials or screen recordings. Pro users get expanded sections covering every module. Lite users get a focused summary of core diagnostics. Either way, the report is self-contained, portable, and immediately useful.
This is professional diagnostic tooling — built to reveal and explain WordPress issues, not automate solutions. Completely non-invasive: it provides insight into issues currently affecting your site, as well as potential future risks.
Right now, your site is almost certainly throwing PHP errors nobody is reading. A plugin that was updated last week may be the cause — but without error log correlation, you'll never connect those dots. A single bloated autoload table can add hundreds of milliseconds to every page load. A failing cron job queues silently and spikes on the next visitor. A conflict between two plugins makes both unreliable in ways that are impossible to reproduce consistently.
The sites that run smoothly aren't lucky — they're monitored. The difference between a five-minute fix and a weekend emergency is knowing the problem exists, knowing which plugin caused it, and knowing what changed.
WP Health Inspector gives you that knowledge — without the risk of touching anything.
Root Cause Analysis names the responsible plugin, gives you the WP-CLI command, and shows a deactivation link — all in one view.
Pre-Update Impact Analysis scores every pending update with a 0–100 Blast Radius Score before you click anything.
