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.
Key Features:
- Troubleshooting Mode: Activate a unique, session-based “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:
- Simulate Plugin Deactivation: Selectively “deactivate” plugins. The plugin’s assets and code will be disabled for your session only.
- Simulate Theme Switching: Preview any installed theme, while the public-facing site continues to use the active theme.
- Live Debugging: Safely enable
WP_DEBUG
with a single click from the admin dashboard. Errors are logged todebug.log
without being displayed on the site, and you can view the log file directly in the plugin’s interface. - Comprehensive Site Information: 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.
- Copy to Clipboard: A one-click button allows you to copy all the site information, making it incredibly easy to share with support forums or developers.
- Safe Debugging & Cache Bypassing: All troubleshooting actions are session-based. The plugin automatically attempts to bypass caching when Troubleshooting Mode is active, ensuring your changes are reflected instantly.
- User-Friendly Interface: An intuitive dashboard interface makes it easy to access all features.
- Admin Notices: Clear notices alert you when Troubleshooting Mode is active.
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.
