Ultimate DebugBar

Ultimate debug bar for your WordPress website. On each page of your website a neat debug bar will be displayed with the following info:

• PHP version
• Request execution time
• Request memory consumption
• WordPress-related PHP constants defined in your wp-config.php file
• All website options (wp_options)
• Request data
• Timeline (waterfall) where you can see which portion of execution takes too much time
• List of all hooks triggered on the page whose execution time exceeds 1ms, along with some stats
• List of all database queries performed on the page, along with their source and execution time
• Last 100 lines of your debug.log file (if it exists in wp-content)
• List of loaded PHP files (categorized)

Besides that, it will track request data/hooks/db queries/mem. consumption in AJAX calls too (beta).

This plugin is meant to be used during development and/or debugging only. Only administrators and network administrators (in multi-site environment) can see the debugbar, unless the WP_DEBUG is set to true. In that case, everyone will see the debugbar.

Q: AJAX requests are not working when plugin is active
A: Your server is blocking Ultimate Debugbar. If you’re running nginx, (check this)[https://stackoverflow.com/questions/23844761/upstream-sent-too-big-header-while-reading-response-header-from-upstream].

Q: AJAX requests are not being diplayed in the debugbar
A: Plugin is trying to send too much data in the headers. I’m afraid there’s no solution for this yet.

Q: How do I disable tracking AJAX requests?
A: Add the following code to your wp-config.php:

define('ULTIMATE_DEBUG_AJAX', false);

1. 

   List of all database queries with their timings

2. 

   List of (slow) hooks lasting over 1ms in an AJAX request

3. 

   Deserialized/formatted config options

4. 

   Timeline (waterfall) of WP execution (TTFB)
