## 描述
Adds a debug menu to the admin bar that shows query, cache, and other helpful debugging
information.
A must for developers!
When `WP_DEBUG` is enabled it also tracks PHP Warnings and Notices to make them
easier to find.
When `SAVEQUERIES` is enabled the mysql queries are tracked and displayed.
To enable these options, add the following code to your `wp-config.php` file:
```
define( 'WP_DEBUG', true );
define( 'SAVEQUERIES', true );
```
Add a PHP/MySQL console with the [Debug Bar Console plugin](https://wordpress.org/plugins/debug-bar-console/).
There are numerous other add-ons available to get more insight into, for instance,
the registered Post Types, Shortcodes, WP Cron, Language file loading, Actions and
Filters and so on. Just [search the plugin directory for ‘Debug Bar’](https://wordpress.org/plugins/search/debug+bar/).
## 安装
Use automatic installer.

### [Simple and easy](https://wordpress.org/support/topic/simple-and-easy-536/)
[Lene](https://profiles.wordpress.org/lenesachs/) 2026 年 3 月 27 日
It works…
### [Works perfectly](https://wordpress.org/support/topic/works-perfectly-2898/)
[Michael Galli](https://profiles.wordpress.org/galliweb/) 2025 年 11 月 14 日
Finding bugs is very easy and efficient with that plugin. I can highly recommend
it.
### [Seemingly abandoned](https://wordpress.org/support/topic/seemingly-abandoned/)
[James Hunt](https://profiles.wordpress.org/bonkerz/) 2025 年 7 月 11 日
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.
### [Getting translation errors in WP 6.7](https://wordpress.org/support/topic/getting-translation-errors-in-wp-6-7/)
[Traci Larson](https://profiles.wordpress.org/treysea/) 2025 年 5 月 23 日
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 incorrectly. I hope there will be an update soon!
### [it must be!](https://wordpress.org/support/topic/it-must-be-2/)
[Marcin Pietrzak](https://profiles.wordpress.org/iworks/) 2023 年 11 月 22 日
A plugin without which I cannot imagine my work. It would definitely be much more
difficult.
### [Helpful tool](https://wordpress.org/support/topic/helpful-tool-30/)
[Mehedi Hasan](https://profiles.wordpress.org/b-07/) 2023 年 7 月 29 日
Simple and useful.
