Description
Working with WP_DEBUG 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. No code editing needed.
Choose which errors to see
Turn off specific PHP error types independently:
- Notices – informational messages that rarely indicate a real problem
- Deprecated – warnings about outdated functions, usually from third-party code
- Warnings – optional, keep them on if you’re actively debugging
- Strict – PHP 7 strict standards messages (not applicable in PHP 8+)
Control error display
Three modes for showing errors on screen:
- Inherit – follows your
wp-config.phpsettings (default, non-intrusive) - On – always show errors, useful during active development
- Off – hide all errors from screen even if
WP_DEBUG_DISPLAYis on
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:
- Set a custom log file path (absolute or relative to
wp-content/) - Set a maximum log file size (1–100 MB); the file rotates automatically when the limit is reached
- Defaults to
wp-content/debug.logif no path is specified
Remove the php-error CSS class
When WordPress encounters a PHP error, it adds a php-error class to the <body> 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 (such as Elementor, WooCommerce, or any “A…” plugin) throws an error before GLOBUS Debug Control initializes, those errors won’t be filtered. Enabling the MU-plugin dropin installs a small helper file into wp-content/mu-plugins/ that runs before any regular plugin – ensuring your filter settings apply to all PHP errors from the very start of the request.
Installation
- Upload the
globus-debug-controlfolder to the/wp-content/plugins/directory. - Activate the plugin through the Plugins menu in WordPress.
- Go to Settings GLOBUS Debug Control and configure as needed.
FAQ
-
Does the plugin require WP_DEBUG to be enabled?
-
The plugin is always active, but error filtering only takes effect when
WP_DEBUGis set totrueinwp-config.php. Error display and logging settings work independently ofWP_DEBUG. -
Will it hide errors in AJAX or REST API responses?
-
Yes. Errors are always suppressed from output during AJAX requests, REST API calls, WP-Cron, and WP-CLI – regardless of your display settings. This prevents broken JSON responses.
-
What is the MU-plugin dropin and do I need it?
-
It’s an optional small file installed into
wp-content/mu-plugins/. It makes GLOBUS Debug Control run earlier than any regular plugin, so errors thrown during early plugin initialization are also filtered. Enable it if you see errors from plugins that load before this one. The dropin is removed automatically when the plugin is deactivated. -
Where is the log file saved?
-
By default, errors are logged to
wp-content/debug.log. You can set a custom path in the plugin settings. The log file rotates automatically once it exceeds the size limit you set. -
Can I use this on a live site?
-
Yes. The recommended setup for a production site is: suppress all error types, disable error display, enable logging to a file, and keep the
php-errorclass removal active.
