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.

Do you get frustrated trying to work out what the template file you’re editing is? Ever had to echo/print some text to see if WordPress is picking up the file you expect it to?
If yes, then give this plugin a try, it simply adds a handy dropdown at the top of the admin bar giving you the ability to quickly see what theme template file(s) is being used, as well as what other files are being included, from themes and plugins.
Never get frustrated with creating child themes again, using Template Debugger you can generate a new child theme based on one of the installed parent themes, and Template Debugger does all the leg work! Just fill out the input fields and Template Debugger will create the theme directory, add in the style.css and functions.php
