Erriscope – Error Monitoring for WooCommerce
Find the cause, not just the error.
Erriscope is a WordPress error monitoring and incident diagnostics plugin for site owners, developers, agencies, and WooCommerce stores.
Instead of leaving you with raw log lines, Erriscope groups repeated failures into clear incidents, tracks severity and recurrence, records recovery, and identifies the likely plugin, theme, file, or request area when evidence is available.
Erriscope works as a standalone WordPress monitoring plugin. When WooCommerce is active, it automatically adds read-only checkout, cart, payment, and failed-order monitoring without changing orders, stock, gateways, checkout settings, or customer sessions.
Core features
- Group repeated PHP warnings, fatal errors, and critical failures into incidents
- Track severity, occurrence count, verification, recovery, and recurrence
- Show incident evidence, likely source, file location, business impact, and recommended next steps when available
- Identify likely plugin, theme, WordPress Core, or file attribution when evidence is available
- Monitor frontend, REST API, admin AJAX, and WP-Cron execution paths
- Compare incidents with recent plugin, theme, and PHP file changes
- Receive grouped incident and recovery email digests
- Run local health checks and preserve resolved incident history
- Run a controlled Safe Test Incident without breaking the site or sending an incident alert
- Enable WooCommerce Store Health signals automatically when WooCommerce is active
- Use the complete Free plugin locally without an Erriscope account or license
Safe Test Incident
New users do not have to wait for a real failure to understand the incident workflow. The controlled Safe Test Incident creates a clearly labelled diagnostic warning, demonstrates grouping and incident evidence, sends no incident alert, changes no WooCommerce data, and resolves automatically after verification.
WordPress error monitoring
Erriscope monitors runtime failures while WordPress is executing requests and background work, including PHP warnings, fatal errors, critical runtime failures, local loopback health-check failures, and incident recurrence after recovery.
No runtime monitor can report an error before the affected code executes. Erriscope records supported failures when WordPress runs the relevant request path.
WooCommerce monitoring
When WooCommerce is active, Erriscope adds read-only signals for:
- Checkout exceptions and Store API server failures
- Cart Store API failures
- Repeated payment-failure patterns grouped by gateway
- Failed-order patterns and recovery signals
- Checkout and cart configuration health
Erriscope does not create test orders, process payments, modify stock, change gateway settings, or alter customer sessions. WooCommerce remains optional.
Incident lifecycle and email digests
Repeated occurrences with the same fingerprint remain grouped as one incident. Erriscope increases the occurrence count, verifies whether the signal is still failing, records recovery evidence, and can reopen the incident if the same problem returns.
Incident bursts can be combined into digest emails instead of generating one message for every repeated occurrence. Local email uses the existing WordPress wp_mail() transport, including an SMTP plugin when configured.
Safe fatal capture
Erriscope can install a managed wp-content/fatal-error-handler.php drop-in to preserve fatal-error context before WordPress Recovery Mode replaces it.
It never overwrites a fatal handler owned by another plugin or hosting provider. If another handler exists, Erriscope reports the conflict and continues using the monitoring paths that remain available.
Privacy by design
Erriscope Free stores incident data locally on the WordPress installation. It does not require an account, license, payment connection, or external monitoring service for local diagnostics.
The Free plugin does not send incident data to Erriscope servers. Local availability checks may request the site’s own URL and local Erriscope health endpoint.
Optional Pro add-on
Erriscope Free is a complete local monitoring and diagnostics plugin. A separately distributed commercial add-on can extend it with independent 24/7 remote monitoring, server-side downtime alerts, advanced notification channels, deeper WooCommerce payment diagnostics, longer history, and private commercial updates. The commercial add-on is not included in this WordPress.org package.
