Lumiblog Debug Log Inspector

Lumiblog Debug Log Inspector is a powerful quality assurance and debugging tool that monitors your WordPress debug.log file for plugin-specific errors. Unlike other debug tools, it allows you to monitor ANY WordPress plugin through an easy-to-use settings interface – no coding required!

Key Features

• Universal Plugin Monitoring: Add any WordPress plugin to monitor through a simple settings page
• No Code Editing: Add/edit/delete monitored plugins through the WordPress admin interface
• Real-time Monitoring: Automatically scans your debug.log file for errors
• Visual Status Indicators: Color-coded admin bar display (Green = OK, Red = Errors Found, Gray = Debug Logging Disabled)
• Auto-Detection: Option to only monitor plugins that are currently active
• Plugin-Specific Tracking: Individual status for each monitored plugin
• Last Error Display: Shows the most recent error message for quick diagnosis
• Duplicate Prevention: Smart validation prevents adding the same plugin twice
• Enable/Disable Plugins: Toggle monitoring for specific plugins without deleting them
• Lightweight: Minimal performance impact with efficient log reading
• Well-Organized Code: Modular file structure for easy maintenance and customization

Perfect For

• QA Teams testing multiple plugins
• Plugin Developers debugging their own plugins
• WordPress Developers monitoring client sites
• Agency Teams managing multiple WordPress installations
• Anyone who wants to keep track of plugin errors

How It Works

1. Install and activate the plugin
2. Go to Settings > Log Inspector
3. Add any plugin you want to monitor by providing:
   • Plugin Name (e.g., “WooCommerce”)
   • Plugin File Path (e.g., “woocommerce/woocommerce.php”)
   • Search Terms (e.g., “woocommerce, wc-“)
4. Check the admin bar for real-time error status

Requirements

To use this plugin effectively, you need to enable WordPress debug logging by adding these constants to your wp-config.php file:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );

Testing the Plugin

To verify Lumiblog Debug Log Inspector is working correctly, follow these steps:

Step 1: Enable Debug Logging

Add to your wp-config.php:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );

Step 2: Add a Plugin to Monitor

1. Go to Settings > Log Inspector
2. Click “Add New Plugin to Monitor”
3. Fill in the form with a plugin you have installed (e.g., WooCommerce)
   • Plugin Name: WooCommerce
   • Plugin File Path: woocommerce/woocommerce.php
   • Search Terms: woocommerce, wc-
4. Click “Add Plugin”

Step 3: Generate a Test Error

Note: Ensure that the test site is running on PHP 8.4+

1. Add this code snippet inside of any active plugin’s main file:

   /**

   • DEBUG LOG INSPECTOR DEMO – PHP 8.4 Warning Trigger
   • REMOVE AFTER DEMO/TESTING!
     */
     add_action( ‘load-index.php’, function() {
     if ( version_compare( PHP_VERSION, ‘8.4.0’, ‘>=’ ) ) {
     $test_array = array( ‘name’ => ‘Debug Log Inspector’ );
     $undefined_value = $test_array[’email’]; // Triggers warning
     error_log( ‘[DLI-DEMO-PHP84] PHP 8.4 warning triggered!’ );
     }
     });

2. Reload the site’s admin dashboard to trigger the error

3. Check your admin bar – it should turn RED

Step 4: View the Debug Log (Optional)

Navigate to wp-content/debug.log to see the actual error entries that were logged.

Clean Up:

1. Remove the test code you added
2. Either delete wp-content/debug.log or clear its contents
3. The admin bar should return to GREEN

For enhanced debugging, you can also add these optional constants to your wp-config.php:
