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>.

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.

Pixelite

WP Safe Mode allows you to view your site temporarily with certain plugins disabled/enabled as well as switching to another theme.
This is particularly useful if you are experiencing problems with a specific plugin or theme and need troubleshoot without it affecting the rest of your site visitors.
Additionally, a loader file can be directly installed via FTP to help you access an inaccessible site due to PHP errors (e.g. blank screens or white screen of death) to help restore it from the admin panel.
<h4>Main Features</h4>
<ul>
<li>Enter Safe Mode for just yourself whilst logged in.</li>
<li>Enable Safe Mode for the whole site.</li>
<li>Admin Bar shortcuts for enabling/disabling Safe Mode.</li>
<li>Restrict Safe Mode to certain IP addresses.</li>
<li>Automatic installation (if file permissions allow).</li>
<li>Fallback to a default WordPress theme or one of your choice in Safe Mode.</li>
<li>Prevent or allow Must-Use plugins from loading in Safe-Mode.</li>
