Web Plura Diagnostics is a free local WordPress problem advisor for site owners, agencies, and admins. It scans wp-admin-side signals and tells you:
<ul>
<li>What is wrong</li>
<li>Why it matters</li>
<li>What business impact it may cause</li>
<li>Who should fix it</li>
<li>What to fix first</li>
</ul>
No cloud account, no tracking, and no frontend scripts are required for the core diagnostics workflow.
<h4>Key Checks</h4>
<ul>
<li>Fix First dashboard with score, priority groups, recommended actions, and recent-change history.</li>
<li>Site Health-style checks for WordPress, PHP, database, HTTPS, debug visibility, updates, cache signals, and key permissions.</li>
<li>Email readiness checks for local mail transport, SPF, DKIM, DMARC, domain alignment, and manual admin-triggered test email results.</li>
<li>Lead Capture Health checks for form plugins, contact pages, SMTP readiness, privacy-page status, and form-plugin updates.</li>
<li>Pre-update Safety checks for inactive plugins, theme updates, commerce plugins, builders, cache plugins, and recovery readiness.</li>
<li>Hosting Advisor checks for memory, cache, cron pressure, upload limits, execution limits, and host-support guidance.</li>
<li>Client-ready diagnostics with problem, impact, owner, urgency, next action, JSON/CSV exports, WP-CLI commands, and multisite network visibility.</li>
</ul>
Good fit for:
<ul>
<li>Site owners who want a clear first-pass health and configuration review</li>
<li>Agencies maintaining multiple WordPress sites</li>
<li>Support teams collecting safe local diagnostics before deeper troubleshooting</li>
<li>WordPress admins who want prioritized actions without telemetry</li>
</ul>

<h3>External Services</h3>
Web Plura Diagnostics is local-first. Diagnostics scans, dashboard rendering, exports, scheduled scans, and helper status checks run inside WordPress by default.
The plugin links to WPlura product, terms, and privacy pages for support and product information:

The public WordPress.org package uses WordPress.org update checks. Direct/private WPlura builds may request a signed WPlura release manifest from https://wplura.com/api/v1/public/plugin-updates/web-plura-diagnostics/manifest and send only the plugin slug, current version, and release channel.
Data, retention, and uninstall behavior:
<ul>
<li>Diagnostics results, history snapshots, explain-mode preference, scheduled-scan settings, export metadata, and manual test-email metadata are stored locally in WordPress options/transients.</li>
<li>Retention settings allow site admins to control how long local diagnostic history and email-test metadata are kept.</li>
<li>Uninstall cleanup removes plugin-owned options, transients, scheduled scan hooks, and local diagnostic metadata.</li>
</ul>
