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 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>
