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>.

Debug Bar

This plugin does a good job.

Extremely useful when debugging own plugins.

Great debugging tool

Very simple and useful.

Very simple and useful

This is a great debugging tool with lots of other supporting plugins available.

Simple and extensible

It is a great help when investigating problematic cases in support of our review plugins

We are using it in our plugin support

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.

Saves you from asking “have you emptied your cache?”.
Forked and updated for todays WordPress and PHP from the original plugin by Paul Clark.
Features
<ul>
<li>Safe to leave running on live sites.</li>
<li>Only refreshes browser cache for a file if it has been modified.</li>
<li>Resolves Content Delivery Network (CDN) issues. No need to purge CDN cache.</li>
<li>Multisite compatible.</li>
<li>“Just works” – no configuration necessary.</li>
</ul>
Requirements
Requires scripts use any of the below functions to load. Almost all files meet these requirements. The only case it doesn’t account for is when URLs are hard-coded. This shouldn’t ever be done, since it can break sites for other reasons.
<ul>
<li><a href="https://codex.wordpress.org/Function_Reference/wp_enqueue_style" rel="nofollow ugc">wp_enqueue_style</a></li>
<li><a href="https://codex.wordpress.org/Function_Reference/wp_enqueue_script" rel="nofollow ugc">wp_enqueue_script</a></li>
<li><a href="https://codex.wordpress.org/Function_Reference/get_stylesheet_uri" rel="nofollow ugc">get_stylesheet_uri</a></li>
</ul>

reBusted!

I always have one or two clients where "its still not working for us"

This is the plugin that solves that. 

Recommend developers/agencies everywhere install this and save them and their clients a bundle of time. 

Thanks for keeping this alive after the last Busted version went AWOL. 

Thanks for keeping this alive


This is a great tool for advanced developer. It saves you from manually versioning your css/scripts or devising your own versioning solutions based on system time which would reload css/js every time, slowing a page load. This ensures only changed styles/scripts are reloaded. Five stars!


A must

Force browsers to load the most recent file if modified.

Debug Bar vs reBusted!
