<p>Fullworks Support Diagnostics makes it easier for plugin developers to troubleshoot issues by automatically collecting diagnostic information and providing powerful debugging tools. It discovers installed plugins and provides a framework for plugin-specific diagnostic data collection.</p>
<p>This plugin should only be activated when instructed by plugin support personnel for diagnostic purposes.</p>
<h4>Key Features</h4>
<ul>
<li><strong>Automatic plugin discovery</strong> – Detects compatible plugins with support-config.json files</li>
<li><strong>System information collection</strong> – Gathers essential WordPress environment data</li>
<li><strong>wp-config.php debug management</strong> – Safely modify debug constants with automatic backups</li>
<li><strong>Shortcode scanning</strong> – Identifies shortcodes used across your site</li>
<li><strong>Freemius integration</strong> – Collects license status and Freemius state for premium plugins</li>
<li><strong>REST API endpoints</strong> – Allows secure remote diagnostics with temporary access links</li>
<li><strong>Sensitive data protection</strong> – Masks API keys and other confidential information</li>
<li><strong>Debug log monitoring</strong> – Checks and displays the most recent log entries</li>
</ul>
<h4>Debug Management</h4>
<p>The plugin can safely manage debug constants in wp-config.php:</p>
<ul>
<li>Enable/disable WordPress debugging with a single click</li>
<li>Automatically creates backups of wp-config.php before any modifications</li>
<li>Clearly marks all changes with comment blocks for easy identification</li>
<li>Safely removes all modifications when the feature is disabled</li>
<li>Monitors debug log files for recent entries</li>
</ul>
<h4>Security Considerations</h4>
<ul>
<li>All wp-config.php modifications require explicit admin confirmation</li>
<li>Access keys can be regenerated at any time</li>
<li>Temporary access links expire after 24 hours</li>
<li>API keys and sensitive data are masked in diagnostic reports</li>
<li>REST API endpoint can be disabled if not needed</li>
</ul>
<h3>Usage Instructions</h3>
<h4>For Site Owners</h4>
<ol>
<li><strong>Only install when directed by support personnel</strong></li>
<li>Go to Tools <span aria-hidden="true" class="wp-exclude-emoji">→</span> Plugin Support Diagnostics in your WordPress admin</li>
<li>If instructed, enable debug management and select appropriate debug constants</li>
<li>Click “Generate Diagnostic Data”</li>
<li>Share the diagnostic information with support using one of these methods:
<ul>
<li>Copy to clipboard</li>
<li>Download as JSON</li>
<li>Use the temporary direct access link (valid for 24 hours)</li>
</ul>
</li>
<li>When troubleshooting is complete, disable any debug options and consider deactivating the plugin</li>
</ol>
<h4>For Plugin Developers</h4>
<p>To make your plugin compatible with Support Diagnostics, create a <code>support-config.json</code> file in your plugin’s root directory. See the example-support-config.json file included in the plugin for reference.</p>

<p>Debug Log Manager Tool is a debug log viewer and WP_DEBUG manager for WordPress. Read, search, group, and clear <code>wp-content/debug.log</code> from inside wp-admin; toggle WP_DEBUG, WP_DEBUG_LOG, WP_DEBUG_DISPLAY, SCRIPT_DEBUG, and SAVEQUERIES from explicit UI controls instead of editing <code>wp-config.php</code>; capture the last fatal error during shutdown; and review slow database queries with their stack trace. Useful as a lightweight alternative to Query Monitor or Debug Bar when you mainly need a clean debug.log reader and explicit debug-constant control.</p>
<p>The plugin focuses on safe first-run behavior: activation does not automatically turn debug mode on, deactivation does not automatically turn it off, and existing debug constants or custom log paths are preserved until you choose to change them.</p>
<p>Use it to inspect the current debug log, search and group log entries, copy useful error details, and make explicit debug configuration changes from the WordPress admin when needed. Advanced tools such as terminal commands, database inspection, Safe Mode, and notifications are available as optional helpers.</p>
<h4>Quick Demo</h4>

<h4>Key Features</h4>
<ul>
<li><strong>Safe First Run</strong>: Activating the plugin does not automatically change WP_DEBUG, WP_DEBUG_LOG, WP_DEBUG_DISPLAY, SCRIPT_DEBUG, SAVEQUERIES, or existing log paths.</li>
<li><strong>Explicit Debug Controls</strong>: Review current debug constant values and update them only through intentional UI actions.</li>
<li><strong>Modern Debug Log Viewer</strong>: View, search, filter, group, copy, and clear debug log entries from a compact WordPress admin interface.</li>
<li><strong>Readable Timeline Rows</strong>: Scan log entries with severity labels, occurrence counts, plugin/source hints, exact timestamps, and copy-as-JSON actions.</li>
<li><strong>Stack Trace Analysis</strong>: Format PHP stack traces and database call chains so long fatal errors are easier to read.</li>
<li><strong>Last Fatal Snapshot</strong>: Capture the latest fatal error during shutdown and show it in the log screen when wp-admin is available again.</li>
<li><strong>Large Log File Preview</strong>: Open the current debug log file inside a modal and safely read the latest 1 MB of large files.</li>
<li><strong>Smooth Upgrade Behavior</strong>: Upgrades preserve existing constants and custom debug log locations instead of replacing your current configuration.</li>
<li><strong>Query Inspector</strong>: Optionally examine database queries when SAVEQUERIES is enabled, including SQL, caller, execution time, and stack trace details.</li>
<li><strong>WP-CLI Style Terminal</strong>: Optionally run guarded WordPress-style commands directly from the browser with command history and auto-completion.</li>
<li><strong>Terminal Settings</strong>: Enable or disable terminal access and database commands from a dedicated settings screen.</li>
<li><strong>Safe Mode</strong>: Optionally isolate plugin conflicts by keeping selected plugins active and restoring the previous state when Safe Mode is turned off.</li>
<li><strong>Email Notifications</strong>: Optionally configure notification email settings, daily summaries, and test email delivery for debug activity.</li>
<li><strong>Admin Bar Debug Toggle</strong>: Quickly review and change WP_DEBUG from the WordPress admin bar when you explicitly choose to.</li>
<li><strong>Dashboard Widget</strong>: See recent debug log activity from the WordPress dashboard.</li>
<li><strong>Custom Log Path Support</strong>: Keep existing custom log paths and use filters to customize the debug log location.</li>
<li><strong>Hardened Admin Routes</strong>: AJAX actions use nonce and capability checks, with guarded file path handling for debug log access.</li>
</ul>
<h4>Debug Constants Available</h4>
<p>These constants can be reviewed and changed from the plugin UI. The plugin does not change them on activation or deactivation.</p>
<ul>
<li><strong>WP_DEBUG</strong> – Enables WordPress debug mode</li>
<li><strong>WP_DEBUG_LOG</strong> – Saves errors to the configured debug log destination</li>
<li><strong>SCRIPT_DEBUG</strong> – Uses development versions of core JS and CSS files</li>
<li><strong>WP_DEBUG_DISPLAY</strong> – Controls whether debug messages display on screen</li>
<li><strong>SAVEQUERIES</strong> – Saves database queries for analysis</li>
</ul>
<h4>Developer Tools</h4>
<ul>
<li><strong>Terminal Commands</strong>: Optionally use WP-CLI style commands like <code>wp core version</code> or <code>wp plugin list</code></li>
<li><strong>Database Explorer</strong>: Optionally run SELECT queries and view results in a formatted table</li>
<li><strong>Stack Trace Analysis</strong>: Visualize error stack traces for easier debugging</li>
<li><strong>Hook Inspector</strong>: View all registered hooks and their callbacks</li>
<li><strong>Environment Detection</strong>: Development features are automatically hidden in production</li>
<li><strong>Copy JSON</strong>: Copy structured log entries for support tickets or developer handoff</li>
<li><strong>File Viewer</strong>: Inspect the debug log file without leaving the WordPress admin screen</li>
</ul>
<blockquote>
<p><strong>Developer API</strong>: Use filters like <code>wp_dlct_log_file_path</code> and <code>dlct_debug_file_path</code> to customize log path behavior.</p>
</blockquote>
<p>Please note: Configuration changes are made only by explicit UI actions. Deactivating the plugin does not automatically restore, remove, enable, or disable WordPress debug constants.</p>


Debug Log Manager Tool

Awesome!

Helps us a lot with development :)

it's exactly what i am after for. instead of connecting to ftp, opening wp-config.php, editing the constants, saving, uploading, reloading site, opening debug.log and deleting it and so on … you simple enable the toggle and look into the logs right in wordpress with nice styling so you can easily distinguish between warning and errors. 
in the future i would like to see more toggles for instance for WP_DEBUG_DISPLAY. for some reason this is missing?! 

simple but good


My go-to debugging plugin for 500 internal server errors and anything that's trickier to track. Good job.


Super useful


Fantastic plugin with an easy interface for browsing. Thank you so much for making it available for free!


Fantastic & easy to use.


The plugin used to work very well, but with the latest update the debug log cannot be cleaned. This has been reported as a bug 2 months ago with no response and no other update. This is why I'm giving the plugin 2 stars. There are other plugins that work better.



--- EDIT ---



Recently I tested the plugin again and it has improved by a lot. I see new functions and - so far - zero bugs. Well done. I improve my rating. Keep up the good work.


Much improved over time


Using this plugin for more than 3 years, and its my favourite one to debug!


Great plugin

Read, search, and clear WordPress debug logs from wp-admin. Toggle WP_DEBUG and inspect errors without FTP.
