<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>

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

The "Debug Log Config Tool" simplifies debugging. Toggle logging,queries , view levels, clear logs from dashboard.
