The fastest and easiest way to switch debug mode on/off and view PHP info directly from the admin.
Toggle debug mode ( <code><?php define( 'WP_DEBUG', true ); ?></code> ) and view PHP version and info ( <code><?php phpinfo(); ?></code> ).
How?
Simply activate the plugin to enable and deactivate the plugin to disable them when you’re done debugging.
Why?
There are a dozen other debugging plugins that already do this (more or less), so why create another?
Well, I already tried them all, and they just felt clunky and unnecessarily overcomplicated. I got tired of having to manually switch debug mode on and off and these other plugins didn’t offer a simple way to do that without also adding a bunch of other bells and whistles that I found to just be in the way, so I made something simpler.
