A plugin that will display debug information without have to use print_r() or var_dump()! Note: WebDevStudio has created [WP-Devel](http://wordpress.
Krumo comes with some default styles: default, blue, green, orange, and scablon.com. It is set to default which works the best with the default WordPress theme. If you would like to change it you can go to the "krumo" folder of the plugin and edit the "selected" value in the krumo.ini file (you might have to adjust the styles depending on how CSS inheritance from your theme throws things off).
I have most of the Krumo API in the plugin, but you can add/remove at your lesiure. If you want to check a variable then simply add to lines 14, but you can see on line 14 that I had to declare WordPress variables as global, because the content is outside the loop. Simply add a global variable to line 12 if needed.
Be sure to check the documentation for their API if need be.
