DebugZen is the ultimate developer tool for WordPress troubleshooting. It gives administrators a powerful, focused dashboard screen for managing WordPress debugging settings and diagnosing fatal errors, warnings, and notices in real time.

If you have ever struggled with finding the debug.log file, or if you need an intuitive error log viewer right inside your WordPress admin area, DebugZen makes it effortless to monitor your site’s health and troubleshoot issues without relying on FTP or SSH.

The plugin uses the battle-tested WP Config Transformer library to read, add, and update these constants in wp-config.php:

WP_DEBUG
WP_DEBUG_LOG
WP_DEBUG_DISPLAY

DebugZen does not use fragile regex or string replacement to modify configuration constants.

Diagnostic Log Viewer & Smart Log Grouping

Instead of raw, unformatted text files that consume excessive memory, DebugZen provides a structured, searchable diagnostic interface:

Smart Log Grouping: Automatically consolidates repeated identical errors into single cards with occurrence counts and first/last seen timestamps.
Source Code Context: Expandable preview showing the exact lines of code surrounding an error, complete with line numbers, error highlighting, and a direct “View in Editor” jump action.
Severity Filtering & Search: Instant debounced search and filtering across Fatal Errors, Warnings, Notices, Deprecations, and stack traces.
Real-Time Live Tail: High-performance streaming that reads newly appended log bytes using byte offsets without polling full files or exhausting PHP memory.
Log Rotation & Size Management: Monitor debug log size with visual thresholds, automatic truncation, or timestamped archival rotation.
Secure Management: Restrict every action to administrators with manage_options, protected by nonces and server-signed HMAC authentication.
Zero External Dependencies: Operates 100% locally with no telemetry, tracking, or remote CDNs.
