A super useful plugin for all developers
By Plugin Author, for WP 4.6

Debug Bar (and it's many add-ons) is a super useful plugin for all developers.

Cleaner notifications of PHP Notices and Warnings, get notifications about notices and warnings on XHR requests, and quickly see what site_id you are on a Multisite install (in addition to the PHP / MySQL versions for single site).

Plugin doesn't work well in PHP7-fpm
By , for WP 4.5.3

Hello everyone.
This plugin is useful, however, it doesn't works well on php7-fpm.
Sometimes it crushed php7/nginx, very often admin-ajax requests doesn't work.
Authors, please apply the patch to php7! Your plugin is awesome, however the progress isn't stay still!


It works and it saves me a lot of time!

To those that have problems making this plugin work: Debug Bar is extensible and requires you to do further actions in order to be useful. For example:

1. Install "Log Viewer" (https://wordpress.org/plugins/log-viewer/) to have a tab where you can see debug.log in real time. This works only if you have the following options in your wp-config.php: "define('WP_DEBUG', true);" and "define('WP_DEBUG_LOG', true);".

2. Install "Debug Bar Console" (https://wordpress.org/plugins/debug-bar-console/) to have a tab where you can directly execute PHP code and MySQL queries. Very useful to quickly test code instead of using functions.php.

3. Set "define('SAVEQUERIES', true);" in wp-config.php to have a tab where you can inspect all database calls and their execution time. WARNING: this feature eats a lot of resources, so make sure you disable it on a live website.

neat little tool
By , for WP 4.5

Neat little tool to review errors and warnings without having to open or resfresh /wp-content/debug.log in an editor in real-time. 4 out of 5 stars as it's pretty basic, expected a little more. Although it's definitely a must-have for every WP admin or developer.

Not working

When we click on "Debug" in admin bar, we get the following (see screenshot link).

Plugin is enabled, but plugin does not seem to be enable. Tested on 3 installs.


Best of luck with development. Sounds like a neat tool, but we did not find it useful.

Deprecated methods on PHP7
By , for WP 4.5-alpha-36255

Plugin throws error on PHP7

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; Debug_Bar has a deprecated constructor in /home/sandboxo/public_html/wpdev/wp-content/plugins/debug-bar/debug-bar.php on line 20

This bug already has been reported a while back and the solution has been posted too. But the people responsible for this plugin simply cannot care less it seems and this being a plugin by the WordPress Foundation makes you wonder what the real priority of them is to switch to PHP7...

Not working

Sounds good, but simply not working on 4.4. Needs update :(
