Adds a debug menu to the admin bar that shows query, cache, and other helpful debugging information.
A must for developers!
When <code>WP_DEBUG</code> is enabled it also tracks PHP Warnings and Notices to make them easier to find.
When <code>SAVEQUERIES</code> is enabled the mysql queries are tracked and displayed.
To enable these options, add the following code to your <code>wp-config.php</code> file:
<pre><code>define( 'WP_DEBUG', true );
define( 'SAVEQUERIES', true );
</code></pre>
Add a PHP/MySQL console with the <a href="https://wordpress.org/plugins/debug-bar-console/" rel="ugc">Debug Bar Console plugin</a>.
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 <a href="https://wordpress.org/plugins/search/debug+bar/" rel="ugc">search the plugin directory for ‘Debug Bar’</a>.

I couldn't do without it

Helpful tool


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


it must be!


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.


Seemingly abandoned

Adds a debug menu to the admin bar that shows query, cache, and other helpful debugging information.

Cron Logger

This plugin works but did not cleanup its table and data in options table in my DB.
