外掛說明
將能顯示查詢、快取及其他實用偵錯資訊的偵錯選單新增至工具列。
開發者必備外掛！
啟用 WP_DEBUG 後，系統便會開始追蹤 PHP 警告及通知，方便網站管理員尋找及查詢。
啟用 SAVEQUERIES 後，系統便會追蹤及顯示 MySQL 查詢。
如需啟用這些設定，請將以下程式碼新增至網站的 wp-config.php 檔案中：
define( 'WP_DEBUG', true );
define( 'SAVEQUERIES', true );
使用 Debug Bar Console 外掛便能加入 PHP/MySQL 主控台。
外掛目錄中還有許多可獲得更多深入解析資訊的附加元件，這些附加元件可取得網站內的已註冊內容類型、短代碼、WP Cron，語言套件載入狀況、動作及篩選器等資訊。如需取得這些附加元件，請在外掛目錄中搜尋「Debug Bar」。

Finding bugs is very easy and efficient with that plugin. I can highly recommend it.

Debug Bar is still listed in WordPress’s own developer documentation as a go-to debugging tool, yet it hasn’t been updated in over a year and throws PHP errors. It’s a clear example of Automattic promoting a tool while failing to maintain it – a pattern that’s become too common. For a plugin they recommend, its neglect is frustrating and undermines developer trust.

This is a very useful plugin, but I am getting errors when WP_DEBUG is set to true based on the updates in WordPress 6.7.
Notice: Function _load_textdomain_just_in_time was called <strong>incorrectly</strong>. I hope there will be an update soon!

A plugin without which I cannot imagine my work. It would definitely be much more difficult.

Simple and useful.

Where is the debug? Only memory usage is displayed… Where are the usage instructions?
