Working with <code>WP_DEBUG</code> enabled often floods the screen with notices and deprecation warnings from third-party plugins and themes – things you neither wrote nor can fix. GLOBUS Debug Control lets you filter out the noise and focus on what actually matters.
All settings are available in Settings – GLOBUS Debug Control. The plugin provides eight tabs: Settings, WP_DEBUG, Error Log, Cron Tasks, Transients, Autoloaded, HTTP Log, and Constants. No code editing needed.
<h4>Settings tab</h4>
Choose which errors to see
Turn off specific PHP error types independently:
<ul>
<li>Notices – informational messages that rarely indicate a real problem</li>
<li>Deprecated – warnings about outdated functions, usually from third-party code</li>
<li>Warnings – optional, keep them on if you are actively debugging</li>
<li>Strict – PHP 7 strict standards messages (not applicable in PHP 8+)</li>
</ul>
Control error display
Three modes for showing errors on screen:
<ul>
<li>Inherit – follows your <code>wp-config.php</code> settings (default, non-intrusive)</li>
<li>On – always show errors, useful during active development</li>
<li>Off – hide all errors from screen even if <code>WP_DEBUG_DISPLAY</code> is on</li>
</ul>
Errors are always hidden automatically during AJAX requests, REST API calls, WP-Cron, and WP-CLI, so your API responses stay clean regardless of the display setting.
Error logging
Enable logging to capture errors in a file instead of (or in addition to) showing them on screen:
<ul>
<li>Set a custom log file path (absolute or relative to <code>wp-content/</code>)</li>
<li>Set a maximum log file size (1-100 MB); the file rotates automatically when the limit is reached</li>
<li>Defaults to <code>wp-content/debug.log</code> if no path is specified</li>
</ul>
Remove the php-error CSS class
When WordPress encounters a PHP error, it adds a <code>php-error</code> class to the <code><body></code> tag, which can break your page layout. This option removes it via both CSS and JavaScript so your front-end and admin look normal even in debug mode.
Early error interception (optional)
WordPress loads plugins in alphabetical order. If another plugin throws an error before GLOBUS Debug Control initialises, those errors will not be filtered. Enabling the MU-plugin dropin installs a small helper file into <code>wp-content/mu-plugins/</code> that runs before any regular plugin, ensuring your filter settings apply from the very start of the request. The dropin is removed automatically when the plugin is deactivated or uninstalled.
<h4>WP_DEBUG tab</h4>
Toggle the five most important debug constants directly from the admin panel without editing <code>wp-config.php</code>:
<ul>
<li><code>WP_DEBUG</code> – master debug switch</li>
<li><code>WP_DEBUG_LOG</code> – write errors to a log file</li>
<li><code>WP_DEBUG_DISPLAY</code> – show errors on screen</li>
<li><code>SCRIPT_DEBUG</code> – use unminified core JS/CSS</li>
<li><code>SAVEQUERIES</code> – log all database queries</li>
</ul>
The plugin locates your <code>wp-config.php</code> automatically and patches it in place, adding the constant if it is missing or updating the existing value. Commented-out defines and block-comment sections are never touched. The current status of <code>WP_DEBUG</code> is always visible as a badge in the plugin header.
<h4>Error Log tab</h4>
Displays the contents of your <code>debug.log</code> file directly in the admin panel using a CodeMirror editor with line numbers. Lines are color-coded by severity: fatal/parse errors, warnings, notices/deprecations, and cron-related messages. The log is paginated (200 lines per page), supports live polling for new entries, and can be downloaded or cleared with one click. Large log files (over 2 MB) are read from the tail to keep memory usage low.
<h4>Cron Tasks tab</h4>
Lists all scheduled WordPress cron events with hook name, next run time, recurrence interval, and arguments. Summary cards show total events, overdue count, orphaned hooks, and duplicates. Overdue events are highlighted. You can run any event immediately or delete orphaned hooks directly from the table.
<h4>Transients tab</h4>
Displays database-stored WordPress transients from the options table with key name, data size, and expiration time. Transients stored in an external object cache (Redis, Memcached) are not shown. Expired transients are highlighted. You can delete individual transients or purge all expired ones in one click. Summary cards show total count, expired count, and total data size.
<h4>Autoloaded tab</h4>
Lists autoloaded options from <code>wp_options</code> sorted by data size (top 200). Shows the option name and value size. Summary cards display total autoloaded row count and total payload size with warnings when thresholds are exceeded (over 800 KB or over 100 rows). This is a read-only diagnostic view to help identify options that inflate every WordPress request.
<h4>HTTP Log tab</h4>
Captures outgoing WordPress HTTP API requests (<code>wp_remote_get</code>, <code>wp_remote_post</code>, etc.) via the <code>http_api_debug</code> hook. Capturing must be explicitly enabled and stores up to 100 entries (6-hour TTL). Each entry shows the request URL, HTTP method, status code, response time, and transport class. Useful for spotting slow or failing external API calls.
<h4>Constants tab</h4>
Displays all WordPress-related PHP constants defined at runtime, grouped by category: Debug, Performance, Security, Database, Auth and Salts, Paths, and Other WP_* constants. Sensitive values (database password, auth keys, salts) are automatically masked. This is a read-only reference view.

GLOBUS Debug Control

WordPress debug toolkit: filter errors, toggle WP_DEBUG, view error logs, monitor cron, transients, HTTP requests, and more.

Debug Log Manager Tool is a debug log viewer and WP_DEBUG manager for WordPress. Read, search, group, and clear <code>wp-content/debug.log</code> from inside wp-admin; toggle WP_DEBUG, WP_DEBUG_LOG, WP_DEBUG_DISPLAY, SCRIPT_DEBUG, and SAVEQUERIES from explicit UI controls instead of editing <code>wp-config.php</code>; capture the last fatal error during shutdown; and review slow database queries with their stack trace. Useful as a lightweight alternative to Query Monitor or Debug Bar when you mainly need a clean debug.log reader and explicit debug-constant control.
The plugin focuses on safe first-run behavior: activation does not automatically turn debug mode on, deactivation does not automatically turn it off, and existing debug constants or custom log paths are preserved until you choose to change them.
Use it to inspect the current debug log, search and group log entries, copy useful error details, and make explicit debug configuration changes from the WordPress admin when needed. Advanced tools such as terminal commands, database inspection, Safe Mode, and notifications are available as optional helpers.

<blockquote>
Developer API: Use filters like <code>wp_dlct_log_file_path</code> and <code>dlct_debug_file_path</code> to customize log path behavior.
</blockquote>
Please note: Configuration changes are made only by explicit UI actions. Deactivating the plugin does not automatically restore, remove, enable, or disable WordPress debug constants.

Debug Log Manager Tool

Awesome!

Helps us a lot with development :)

it's exactly what i am after for. instead of connecting to ftp, opening wp-config.php, editing the constants, saving, uploading, reloading site, opening debug.log and deleting it and so on … you simple enable the toggle and look into the logs right in wordpress with nice styling so you can easily distinguish between warning and errors. 
in the future i would like to see more toggles for instance for WP_DEBUG_DISPLAY. for some reason this is missing?! 

simple but good


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


Super useful


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


Fantastic & easy to use.


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.



--- EDIT ---



Recently I tested the plugin again and it has improved by a lot. I see new functions and - so far - zero bugs. Well done. I improve my rating. Keep up the good work.


Much improved over time


Using this plugin for more than 3 years, and its my favourite one to debug!


Great plugin

Read, search, and clear WordPress debug logs from wp-admin. Toggle WP_DEBUG and inspect errors without FTP.
