This plugin sets the following debug constants in <code>wp-config.php</code> on plugin activation and removes them on plugin deactivation. Any errors will result in a PHP Exception being thrown. Debug constants per <a href="https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/" rel="nofollow ugc">Debugging in WordPress</a>.
Default settings:
<pre><code>define( 'WP_DEBUG_LOG', true );
define( 'SCRIPT_DEBUG', true );
define( 'SAVEQUERIES', true );
</code></pre>
  
 @ini_set( ‘display_errors’, 1 ); is set when the plugin is active. <code>WP_DEBUG</code> is set to true when the plugin is first run, thereafter it can be turned off in the Settings.
The Settings page allows the user to set the following.
<pre><code>define( 'WP_DEBUG', true ); // Default on initial plugin installation.
define( 'WP_DEBUG_DISPLAY', false ); // Default when not declared is true.
define( 'WP_DISABLE_FATAL_ERROR_HANDLER', true ); // WordPress 5.2 WSOD Override.
</code></pre>
When the plugin is deactivated best efforts are made to re-add pre-existing constants to their former state. When the plugin is activated the default settings and any saved settings are restored.
This plugin uses the <a href="https://github.com/wp-cli/wp-config-transformer" rel="nofollow ugc">wp-cli/wp-config-transformer</a> command for writing constants to <code>wp-config.php</code>.
<a href="https://github.com/norcross/debug-quick-look" rel="nofollow ugc">Debug Quick Look</a> from Andrew Norcross is included with this plugin to assist in reading the debug.log file. If you already have this plugin installed you should delete it when WP Debugging is not active.
<a href="https://wordpress.org/plugins/query-monitor/" rel="ugc">Query Monitor</a> and <a href="https://wordpress.org/plugins/debug-bar/" rel="ugc">Debug Bar</a> plugins are optional dependencies to aid in debugging and troubleshooting. The notice for installation will recur 45 days after being dismissed.
If you have a non-standard location for your <code>wp-config.php</code> file you can use the filter <code>wp_debugging_config_path</code> to return the file path for your installation.
The filter <code>wp_debugging_add_constants</code> allows the user to add constants to <code>wp-config.php</code>.
The filter returns an array where the key is the name of the constant and the value is an array of data containing the value as a string and a boolean to indicate whether or not the value should be passed without quotes.
<pre><code>$my_constants = [
 'my_test_constant' =>
 [
 'value' => 'abc123',
 'raw' => false,
 ],
 'another_test_constant' => [ 'value' => 'true' ],
];
</code></pre>
The <code>value</code> option contains the constant’s value as a string.
The <code>raw</code> option means that instead of placing the value inside the config as a string it will become unquoted. The default is <code>true</code>. Set as <code>false</code> for non-boolean values.
Example:
<pre><code>add_filter(
 'wp_debugging_add_constants',
 function( $added_constants ) {
 $my_constants = [
 'my_test_constant' => [
 'value' => '124xyz',
 'raw' => false,
 ],
 'another_test_constant' => [ 'value' => 'true' ],
 ];
 return array_merge( $added_constants, $my_constants );
 },
 10,
 1
);
</code></pre>
This will create the following constants.
<pre><code>define( 'MY_TEST_CONSTANT', '124xyz' );
define( 'ANOTHER_TEST_CONSTANT', true );
</code></pre>

WP Debugging

This helps me support customers and get better debugging information about errors happening on their site without having to ask for sensitive login info. Simple and does a great job, I've used it or recommended it a dozen times in the last month.

Great support tool

I can't tell you the number of times I've had to handle a support request that involved a white screen. Thank you, @afragen, for building this awesome tool to help define constants for a file that isn't easily accessible without passing around credentials.

Super Handy!

Thanks for the useful plugin, we're going to start recommending this to our customers.

Useful Plugin

Thank you for this useful and beautiful plugin, helps me a lot.

Very useful

Quick access to the log files speeds up development!

Great plugin

With this plugin it's at last possible to debug a remote site wihtout having access to the cpanel!

Very useful!


Every time I come across an obscure problem on WordPress sites, I start looking for it by installing this plugin.Thanks to the developers for a great tool!


Perfect tool for debug.

Yet another one of your plugins that I love and use all the time!  Thank you.  (Side note: is there a place to buy you a coffee or donate for your time?)

Another great debugging plugin


I've been using the WP Debugging plugin since 2024, and it has been a lifesaver. The error log feature alone helped me track down several issues that would have taken hours to find manually.



The fact that it integrates with Query Monitor is a nice bonus too. If you do any WordPress development or troubleshooting, just install this plugin. Five stars, no hesitation.


Absolutely essential for debugging – saved me countless times!

A support/troubleshooting plugin for WordPress.

Memory Limit Manager makes it incredibly easy to configure your memory limits without manually editing wp-config.php. With a beautiful, user-friendly interface and powerful features, you can increase memory limits with a single click.
<h4>Key Features</h4>
<ul>
<li>One-Click Updates – Change memory limits with a single button click</li>
<li>Quick Presets – Common configurations (128M/256M, 256M/512M, 512M/1G, 1G/2G)</li>
<li>Automatic wp-config.php Backups – Creates timestamped backups of your wp-config.php file before any changes (format: wp-config.php.backup-YYYY-MM-DD-HHMMSS). Keeps 5 most recent backups and auto-restores on failure</li>
<li>Conflict Detection – Identifies if memory limits are defined elsewhere</li>
<li>System Diagnostics – File permissions and writability checks</li>
<li>Manual Fallback – Copy-paste code if automatic updates don’t work</li>
<li>Opcode Cache Clearing – Immediate effect after changes</li>
<li>Beautiful UI – Modern, card-based layout with real-time validation</li>
</ul>
<h4>Why Use This Plugin?</h4>
Manually editing wp-config.php can be: 
– Intimidating for non-technical users 
– Error-prone (syntax errors can break your site) 
– Difficult to verify if changes took effect
Memory Limit Manager solves all these problems with a safe, user-friendly interface that handles everything automatically.
<h4>What It Does</h4>
This plugin allows you to configure two WordPress memory limit constants: 
1. WP_MEMORY_LIMIT – Controls memory available on the frontend (default: 40M) 
2. WP_MAX_MEMORY_LIMIT – Controls memory available in admin area (default: 256M)
Increasing these values can help resolve: 
– “Memory exhausted” errors 
– Plugin/theme activation failures 
– Image upload problems 
– Slow admin performance
<h4>Automatic Backup System</h4>
For your safety, the plugin automatically backs up your wp-config.php file before making any changes:
<ul>
<li>Backup File Format: wp-config.php.backup-2026-01-15-223045 (timestamped)</li>
<li>Location: Same directory as your wp-config.php file</li>
<li>Number of Backups: Keeps the 5 most recent backups, auto-deletes older ones</li>
<li>Automatic Restore: If any error occurs during update, your original wp-config.php is automatically restored</li>
<li>Manual Restore: You can manually restore any backup file via FTP/cPanel if needed</li>
</ul>
This means you can update memory limits with confidence, knowing your configuration is always protected.
<h4>Security</h4>
<ul>
<li>Nonce verification for CSRF protection</li>
<li>Capability checks (administrator-only access)</li>
<li>Input sanitization and validation</li>
<li>Secure file operations with error recovery</li>
</ul>
