## Description

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.

## FAQ

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);
    ```

This plugin seemed to work fine for me. I wish the timeline ‘Rendering’ was broken
down somehow with more granularity. I have always wished for a tway to tell which
crappy plugin is burning up all the time to render a page.

I don’t understand why this fine little plugin doesn’t have much more fans. It integrates
nicely at the bottom edge of your site-display, offering some KPI at all times, 
ready to be popped open when more information is needed. Its waterfall diagram (
titled « Timeline ») helped me zoom in on a troublemaker in matter of moments; much
more intuitive than quite a few alternatives I have tried before. Thank you, @Avram;
may this live long and gain the audience it deserves.
