<p>The “Debugger & Troubleshooter” plugin provides essential tools for WordPress site administrators to diagnose and resolve issues efficiently. It offers a dedicated section in the WordPress dashboard that displays comprehensive site health information and powerful debugging toggles.</p>
<p><strong>Key Features:</strong></p>
<ul>
<li><strong>Troubleshooting Mode:</strong> Activate a unique, <strong>session-based</strong> “Troubleshooting Mode” for your current browser session. This means any changes you make are temporary and only visible to you. This mode allows you to:
<ul>
<li><strong>Simulate Plugin Deactivation:</strong> Selectively “deactivate” plugins. The plugin’s assets and code will be disabled for your session only.</li>
<li><strong>Simulate Theme Switching:</strong> Preview any installed theme, while the public-facing site continues to use the active theme.</li>
</ul>
</li>
<li><strong>User Role Simulator:</strong> View your site as any other user or role (e.g., Subscriber, Editor) to test permissions and content visibility. This is session-based and includes a safe “Exit” button in the Admin Bar.</li>
<li><strong>Live Debugging:</strong> Safely enable <code>WP_DEBUG</code> with a single click from the admin dashboard. Errors are logged to <code>debug.log</code> without being displayed on the site, and you can view the log file directly in the plugin’s interface.</li>
<li><strong>Comprehensive Site Information:</strong> Get a quick, organized overview of your WordPress environment in collapsible cards. This includes detailed PHP, Database, and Server information, a full list of all themes and plugins with their status, and important WordPress constants.</li>
<li><strong>Copy to Clipboard:</strong> A one-click button allows you to copy all the site information, making it incredibly easy to share with support forums or developers.</li>
<li><strong>PHP Compatibility Checker:</strong> Scan all installed plugins for deprecated functions and syntax that may break when upgrading PHP. Results displayed in a responsive card layout with clear warnings and incompatibility counts.</li>
<li><strong>Conflict Checker:</strong> Systematically identify plugin conflicts through a binary search process. Narrow down suspect plugins by answering whether each group resolves the issue, all within a safe session-based mode.</li>
<li><strong>Safe Debugging & Cache Bypassing:</strong> All troubleshooting actions are session-based. The plugin automatically attempts to bypass caching when Troubleshooting Mode is active, ensuring your changes are reflected instantly.</li>
<li><strong>User-Friendly Interface:</strong> An intuitive dashboard interface makes it easy to access all features.</li>
<li><strong>Admin Notices:</strong> Clear notices alert you when Troubleshooting Mode is active.</li>
</ul>
<p>This plugin is an invaluable tool for developers, site administrators, and anyone who needs to debug WordPress issues without risking site downtime or affecting user experience.</p>
<h3>Usage</h3>
<p>Once the plugin is installed and activated, navigate to <strong>Tools > Debugger & Troubleshooter</strong> in your WordPress dashboard.</p>
<h3>1. Site Information</h3>
<p>The top section provides a comprehensive overview of your WordPress environment, organized into collapsible cards that are closed by default. Click on any card title to expand it and view the details.</p>
<h3>2. Troubleshooting Mode</h3>
<p>This session-based feature allows you to simulate theme switches and plugin deactivations without affecting your live website for other visitors.</p>
<h3>3. User Role Simulator</h3>
<p>Safely view your site as another user or role (e.g., “Subscriber” or “Editor”) without knowing their password. This is perfect for testing capabilities and content restrictions.</p>
<h3>4. Live Debugging</h3>
<p>This section allows you to safely manage WordPress’s debugging features.</p>
<ul>
<li><strong>Enable Live Debug:</strong> Click this button to programmatically enable <code>WP_DEBUG</code> and <code>WP_DEBUG_LOG</code>, while keeping <code>WP_DEBUG_DISPLAY</code> off. This logs errors to <code>wp-content/debug.log</code> without showing them to visitors.</li>
<li><strong>Debug Log Viewer:</strong> A text area displays the contents of your <code>debug.log</code> file, allowing you to see errors as they are generated.</li>
<li><strong>Clear Log:</strong> Safely clear the <code>debug.log</code> file with a click.</li>
</ul>
<h3>5. PHP Compatibility Checker</h3>
<p>Scan all installed plugins for deprecated PHP functions and syntax incompatible with your target PHP version. Select a target version and click “Start Scan” to receive a per-plugin compatibility report with clear warnings and incompatibility counts.</p>
<h3>6. Conflict Checker</h3>
<p>If you are experiencing an issue on your site, use the Conflict Checker to identify the culprit plugin. The plugin systematically deactivates groups of plugins using your session-based Troubleshooting Mode, asking whether the issue persists after each step. Once the culprit is found, you can deactivate it with one click.</p>
