Display debug backtraces for every error generated by PHP, in addition to the standard error outputs configured for your PHP installation.
This includes E_ALL so might contain many more errors than you might expect.
This is useful for finding and debugging issues during development, but could easily break your markup, and is not for users who are not editing code directly. Requires jQuery to be included with your theme.

Krumo is a debugging tool equivalent to print_r() and var_dump(), with the advantage of collapsing array and object values so that it takes less space and let us see only what we really need from complex data.
<a href="http://hikari.ws/krumo/" rel="nofollow ugc">Hikari Krumo</a> ports it to a WordPress plugin, so that Krumo becomes easily available in any WordPress page. Original Krumo has a few bugs fixed and has its options available in an admin page instead of requiring krumo.ini file edited directly.
<h4>Features</h4>
