About this plugin
Debug is a development and production tool that helps you find and fix bugs on your WordPress site (including multisite). php by hand.
What it does for you
- One-click debug flags — toggle WP_DEBUG, WP_DEBUG_LOG, WP_DEBUG_DISPLAY, SCRIPT_DEBUG and SAVEQUERIES directly from the settings page.
- Error log viewer — view, clear and download the tail of your wp-content/debug.log (last 1 MB) right from the admin.
- Real-time email alerts — get notified when errors and warnings occur, with a throttled, level-filtered handler that ignores deprecation notices and suppressed ( @ ) code.
- Safe wp-config editing — a timestamped backup is created automatically before every change, with one-click restore if you ever need to roll back.
Why you can trust it
php (a common credential leak in older debug plugins). All file access is strictly path-guarded, all admin actions are protected with nonces and capability checks, and backups let you revert any change instantly.
Frequently Asked Questions
Is my wp-config.php safe?
Yes. php before every change, and the settings page lets you restore any backup with one click. php is never downloadable from the browser.
Can I use this on a production site?
Yes — and that’s a core use case. Error notifications only fire for meaningful error levels (errors and warnings), never for deprecation notices. Emails are queued and throttled so a busy site won’t flood your inbox, and WP_DEBUG_DISPLAY is kept off by default so errors are not shown to visitors.
Why am I not getting email notifications?
Make sure Email Notification is enabled and a valid address is set, and that wp_mail() works on your host. Only errors and warnings trigger emails (notices and deprecations are filtered out).
The plugin says wp-config.php is not writable. What do I do?
Check your file permissions. php (usually 0644 ). php manually — so you’re never stuck.
What does “Error Log” show?
log, so you can inspect recent errors without loading a huge file. You can clear the log or download it as a plain text file.
Does this work on multisite?
Yes. php edits apply globally, which is the expected behaviour for network-wide debug toggling.
