Description

Debug is a development/production tool for WordPress. It helps you find bugs in your site by letting you toggle WordPress’s built-in debug flags and by emailing you when a runtime error occurs.

Features

  • Toggle WP_DEBUG, WP_DEBUG_LOG, WP_DEBUG_DISPLAY, SCRIPT_DEBUG and SAVEQUERIES from the admin settings page.
  • View, clear and download your wp-content/debug.log tail (last 1 MB).
  • Real-time error email notification with a throttled, level-filtered error handler.
  • Automatic timestamped backup of wp-config.php before every save, plus one-click restore.

How it works

The Debug plugin modifies your wp-config.php file to enable or disable WordPress debug constants, and it reads the tail of your debug.log. A backup of wp-config.php is created automatically before each change so you can always roll back.

Note on file permissions

To edit wp-config.php, your server must allow the plugin to write that file. If it cannot, the plugin shows you the code to paste manually instead.

Security & email notifications

Notifications only fire for meaningful error levels (errors and warnings), never for deprecation notices or suppressed (@) code, and emails are queued and throttled so a busy site won’t flood your inbox or SMTP queue.

FAQ

Is my wp-config.php safe?

Yes. The plugin creates a timestamped backup of wp-config.php before every change, and the settings page lets you restore any backup with one click. wp-config.php is never downloadable from the browser.

Why am I not getting email notifications?

Make sure email notifications are enabled and a valid address is set, and that wp_mail() works on your host. Only errors and warnings trigger emails.

The plugin cannot write wp-config.php

Check your file permissions. If the file is not writable the plugin shows the exact code to paste into wp-config.php manually.

Simple & Great Learning Tool

25 mars 2022
It helps get access to a site’s error log, even for lay users without contacting web hosts or filesystem access. Really useful in debugging in support. Also useful as a teaching/learning tool for basic technical debugging too.

Still Works Great on WP 5.8.2

Thank you for this great plugin which saves time on backing up wp-config.php and turning on debug mode. Eliminates mistakes which might otherwise be introduced when manually changing wp-config.php and allows faster debugging.

Still works

Even though updates have been a while (at least at the time of writing this), the plugin still works well and serves its purpose.

Просто ужас, а не плагин

27 février 2020 1 réponse
С активацией плагина перекосило весь сайт окончательно. Не помогло даже его удаление с сайта. Все записи в админке стали из иероглифов. Хорошо, что получилось из резервной копии на хостинге сайт восстановить, а то слало как то очень хреново от увиденного.

Essential part of a debugger’s toolkit

1 décembre 2019 1 réponse
This plugin has helped me rescue many client sites when they can’t figure out how to enable WP_DEBUGon their own. I know it hasn’t been updated in forever, but it is still working for me as of WordPress 5.3.

Journal des modifications

1.13

  • Security: removed the ability to download wp-config.php (full credential leak). Debug log download now only serves the log via a clean admin-post.php endpoint.
  • Security: added strict path allowlisting + traversal guards to all file reads/writes.
  • Security: automatic timestamped wp-config.php backup before every save + one-click restore UI.
  • Security: error handler now only registers when email notifications are on, filters out deprecation/notice noise, respects error_reporting(), throttles and queues emails, and chains the previous handler.
  • Fix: broken Settings link href (missing closing quote) on the plugin list page.
  • Fix: esc_html_e() misuse replaced with correct escaping (esc_html, esc_attr, esc_url, wp_json_encode-style safe output).
  • Fix: tolerant, case/format-insensitive regex in debug_add_option — no more duplicate define() creation.
  • Fix: nonce action strings standardized + consistent failure notices (no silent no-op, no die()).
  • Fix: read tail capped to 1 MB (was only capping the start offset).
  • Improvements: enqueued CSS instead of inline <style> (CSP-friendly), modernized baseline (PHP 7.4+, WP 5.0+), uninstall.php cleanup.
