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.

Easy PHP Settings provides a user-friendly interface to view and manage crucial PHP and WordPress configurations without needing to manually edit server files. It’s designed for both single-site and multisite installations, giving administrators the power to optimize their environment directly from the dashboard.
Key Features:
<ul>
<li>Manage PHP Settings: Easily modify the 5 core PHP settings (<code>memory_limit</code>, <code>upload_max_filesize</code>, <code>post_max_size</code>, <code>max_execution_time</code>, <code>max_input_vars</code>) through dedicated fields.</li>
<li>Custom php.ini Configuration: Add any additional PHP directives (session settings, timezone, logging, file uploads, etc.) directly in the flexible custom configuration textarea.</li>
<li>Quick Presets: Choose from pre-configured optimization profiles (Default, Performance, WooCommerce, Development, Large Media) that populate both core fields and custom php.ini directives automatically.</li>
<li>WordPress Memory Management: Configure WordPress-specific memory limits including <code>WP_MEMORY_LIMIT</code> and <code>WP_MAX_MEMORY_LIMIT</code> to optimize your site’s performance.</li>
<li>Automatic Configuration: When you save your settings, the plugin automatically generates <code>.user.ini</code> and <code>php.ini</code> files in your WordPress root directory.</li>
<li>Configuration Generator: For locked-down environments, the plugin provides a generator to create configuration snippets that you can manually add to your server files.</li>
<li>PHP Extensions Viewer: View all loaded PHP extensions categorized by type, with indicators for critical missing extensions and recommendations.</li>
<li>Settings Validation: Automatically detects potentially problematic configuration values and warns you before saving.</li>
<li>Settings History: Track all changes made to your settings with the ability to restore previous configurations. Export history as CSV.</li>
<li>Import/Export: Backup your settings as JSON files and migrate configurations between sites effortlessly.</li>
<li>One-Click Reset: Reset to recommended values or server defaults with automatic backup creation.</li>
<li>Helpful Tooltips: Hover over help icons next to each setting to understand what it does and why it matters.</li>
<li>Live Status Checker: A dedicated “Status” tab shows your current server environment, including PHP version, server software, and a comparison of current vs. recommended PHP values.</li>
<li>WordPress Debugging: A “Debugging” tab with on/off switches lets you easily toggle <code>WP_DEBUG</code>, <code>WP_DEBUG_LOG</code>, <code>WP_DEBUG_DISPLAY</code>, and <code>SCRIPT_DEBUG</code> constants in your <code>wp-config.php</code> file.</li>
<li>Multisite Compatible: On multisite networks, settings are managed at the network level by Super Admins.</li>
</ul>
