The fastest and easiest way to switch debug mode on/off and view PHP info directly from the admin.
Toggle debug mode ( <code><?php define( 'WP_DEBUG', true ); ?></code> ) and view PHP version and info ( <code><?php phpinfo(); ?></code> ).
How?
Simply activate the plugin to enable and deactivate the plugin to disable them when you’re done debugging.
Why?
There are a dozen other debugging plugins that already do this (more or less), so why create another?
Well, I already tried them all, and they just felt clunky and unnecessarily overcomplicated. I got tired of having to manually switch debug mode on and off and these other plugins didn’t offer a simple way to do that without also adding a bunch of other bells and whistles that I found to just be in the way, so I made something simpler.

Debug Log Manager allows you to:
<ul>
<li>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 when you need to, and disable it when you’re done. No need to manually edit wp-config.php file. </li>
<li>Create the debug.log file for you in a non-default location with a custom file name for enhanced security. </li>
<li>Copy the content of the default / existing debug.log file 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 view distinct errors and when they last occurred, which is better than looking at the raw log file (potentially) full of repetitive errors. </li>
<li>Quickly find and filter more specific errors for your debugging work.</li>
<li>Make error details easier to read by identifying error source (core / plugin / theme) and separating file path and line number.</li>
<li>Easily view files where PHP errors occurred. This includes WordPress core, plugin and theme files.</li>
<li>Enable auto-refresh 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>Easily clear the debug.log file to save disk space and more easily observe newly occurring errors on your site.</li>
<li>Show an indicator on the admin bar when error logging is enabled.</li>
<li>Add a dashboard widget showing the latest errors logged.</li>
<li>Use <code>error_log()</code> 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>
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.

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.
