<p>Debug Log Manager allows you to:</p>
<ul>
<li><strong>Enable <a href="https://wordpress.org/support/article/debugging-in-wordpress/" rel="ugc">WP_DEBUG</a> with one click to log PHP, database and JavaScript errors</strong> when you need to, and disable it when you’re done. No need to manually edit wp-config.php file. </li>
<li><strong>Create the debug.log file for you</strong> in a non-default location with a custom file name for enhanced security. </li>
<li><strong>Copy the content of the default / existing debug.log file</strong> into the custom debug.log file, and delete the default / existing debug.log file. So there is continuation in logging and enhanced security going forward.</li>
<li>Parse the debug.log file and <strong>view distinct errors and when they last occurred</strong>, which is better than looking at the raw log file (potentially) full of repetitive errors. </li>
<li><strong>Quickly find and filter more specific errors</strong> for your debugging work.</li>
<li><strong>Make error details easier to read</strong> by identifying error source (core / plugin / theme) and separating file path and line number.</li>
<li><strong>Easily view files where PHP errors occurred</strong>. This includes WordPress core, plugin and theme files.</li>
<li><strong>Enable auto-refresh</strong> to automatically load new log entries. No need to manually reload the browser tab, or to <code>tail -f</code> the log file on the command line.</li>
<li><strong>Easily clear the debug.log file</strong> to save disk space and more easily observe newly occurring errors on your site.</li>
<li><strong>Show an indicator on the admin bar</strong> when error logging is enabled.</li>
<li><strong>Add a dashboard widget</strong> showing the latest errors logged.</li>
<li><strong>Use <code>error_log()</code></strong> to output error info into your debug log. e.g. <code>error_log( $error_message )</code> for simple, string-based error message, or <code>error_log( json_encode( $error ) )</code> when inspecting a more complex error info, e.g. array or object.</li>
</ul>
<p>A simpler and more compact version of Debug Log Manager is included as part of the <a href="https://wordpress.org/plugins/system-dashboard/" rel="ugc">System Dashboard plugin</a>, should you prefer a single plugin that does more.</p>

Debug Log Manager – Conveniently Monitor and Inspect Errors

A stitch in time saves nine.

This plugin is so important I have it as the #2 item in my admin menu (below only Dashboard). 

Proactively finding and fixing errors is essential to running a successful site.

This plugin does a simple job, and it does it very well. Some niceties are the JavaScript logging, and the counting of log occurrences. The UI is simple, but appropriate. The developer is responsive. 

I have used a couple of other logger plugins and this is by far the best one.

Must-have plugin


I wish I had found out about this plugin a long time ago. It saves time when debugging client sites.


Such a help

handy plugin


I've been switching from a custom Docker Compose environment to @wordpress/env (aka wp-env) which I still fail to figure out how to quickly tail the PHP debug logs. Is it even possible? They say it is, yet I only ever see the HTTP logs from the web server...



I've added this plugin to my .wp-env.json file so that I always have it available in my test environment now. I'm amazed the infamous Debug Bar plugin doesn't seem to have a way to see the tail of the PHP debug log file..?



My favorite part about this plugin is that repetitive log lines are grouped together in the display, with a note of the number of occurrences. Makes reading the logs much easier at quick glance!



The downside of this plugin is just by the nature that it's a plugin—if you're trying to debug PHP Fatal errors that happen early in execution, they won't be accessible since they would prevent this plugin from running. However, I didn't have a problem with this because I'd let the PHP Fatal happen and then just undo whatever I did to cause the fatal error. After that, I'd just go back to review the error in this plugin's page. Easy!


Makes Debugging in @wordpress/env Possible

Log PHP, database and JavaScript errors via WP_DEBUG with one click. Conveniently create, view, filter and clear the debug.log file.

<p>Custom Error Log allows you to create custom errors in your WordPress theme or plugin with a single function. Great for debugging those long and complex scripts.</p>
<p>Each error can have its own error message making it a lot easier to pin down specific issues in your code. You can also log notices for less serious issues.</p>
<p>All your errors and notices can be viewed conveniently in the WordPress admin area.</p>
<h3>Plugin Features:</h3>
<ul>
<li><strong>Easy Errors:</strong> Create errors with a simple function.</li>
<li><strong>Useful Errors:</strong> Define a custom error message for each error.</li>
<li><strong>Log notices:</strong> Notices can be logged for less serious issues and viewed seperately in the admin area.</li>
<li><strong>Keep Track:</strong> View and moderate all your errors in the WordPress admin area.</li>
<li><strong>Toolbar icon:</strong> The admin toolbar displays how many new errors and notices have occurred on the current page.</li>
</ul>
<h3>Getting Started:</h3>
<p>Install and activate the plugin then in the admin menu go to <em>Tools > Error Log</em>. This will eventually be the page that displays all your latest errors but if you’re just getting started it explains in detail how to start logging custom errors.</p>
<p>In your theme use either of the two built in functions to log an error <code>log_error($message);</code> or a notice <code>log_notice($message);</code>.</p>
<p>When these functions are executed they will log whatever error or notice you want.</p>
<h3>Ongoing Development:</h3>
<p>I have only just started with this plugin and plan on bringing great improvements to it. If you have any ideas please suggest them in the support section.</p>
<h3>Translation:</h3>
<p>The plugin is translation ready but as of yet contains only an English translation file. If you would like to contribute any translations I would be very grateful.</p>
<h3>Please note:</h3>
<p>This plugin is aimed at developers who have at least a basic understanding of PHP. If this isn’t you then you may not find much use from this plugin however if you are unsure how to use any of the functions explained you can post a topic in the support section of the plugin directory and I will do my best to help you.</p>


Custom Error Log

Very promising plugin !
I was developing without debug log and my plugin started to get complicated, I needed a way to debug more easily.
Infos are well presented, it is clear and userfriendly, there is even some infos in the admin toolbar.
Thanks to the Dev for this nice tool !



Promising !

A tool for logging and monitoring custom errors, making debugging complex PHP a breeze.
