## 説明

**Quick debug.log Viewer** lets you quickly inspect your site’s debug.log file without
leaving the WordPress dashboard. Now with a **floating action button (FAB)** and
modal for frontend viewing, searching, and filtering!
 The FAB is now draggable 
and its position is remembered — with a right-click option to reset.

 * Instantly view, scroll, **search**, and filter your `debug.log` contents
 * 🔍 Search and browse logs even from the frontend with a floating action button(
   FAB) and modal
 * Filter logs by type: Fatal, Warning, Notice — or show all
 * Clear the log with a single click (now via AJAX)
 * Download the log for backups or support
 * Load large logs in chunks with the **Load More** button
 * Secure HTML output with escaping to prevent session theft
 * Stack traces are shown in single blocks for better readability
 * Works even if `WP_DEBUG` is off — as long as the file exists

Ideal for developers, site managers, and anyone needing to troubleshoot WordPress
issues fast.

## FAQ

### Where is the debug.log file?

It’s typically located in your `wp-content` directory at `wp-content/debug.log`.

### Do I need to enable anything for this to work?

The plugin works best when `WP_DEBUG` and `WP_DEBUG_LOG` are enabled in `wp-config.
php`, but it can still read the file if it exists and has proper read permissions.

### Can I clear the log from the dashboard?

Yes — just click the “Clear Log” button to safely empty the log file.
