<pre><code>do_action( 'add_debug_info', $var, $label );
</code></pre>
<p>where <code>$var</code> can has any data type.</p>
<ul>
<li>If <code>$var</code> is a string or any simple value, the value is outputted directly.</li>
<li>If <code>$var</code> is an array or object, the output is the same as <code>print_r( $var )</code>.</li>
</ul>
<p>And <code>$label</code> is the description label (optional).</p>
<h4>How to view debug info</h4>
<ul>
<li>Click on <strong>Debug Bar</strong> in the top right of the admin bar</li>

Debug Log – Manager Tool

Awesome!

Helps us a lot with development :)


My go-to debugging plugin for 500 internal server errors and anything that's trickier to track. Good job.


Super useful


The plugin used to work very well, but with the latest update the debug log cannot be cleaned. This has been reported as a bug 2 months ago with no response and no other update. This is why I'm giving the plugin 2 stars. There are other plugins that work better.


Works but has bugs and bad support


Fantastic plugin with an easy interface for browsing. Thank you so much for making it available for free!


Fantastic & easy to use.

The "Debug Log Config Tool" simplifies debugging. Toggle logging,queries , view levels, clear logs from dashboard.
