I like to run my development server with full error notices and WP_DEBUG set to TRUE. Unfortunately a lot of plugins have various E_NOTICE error messages and WordPress deprecated function calls.

So while I am trying to make sure my code is error free it often makes it impossible to use the WordPress admin or reasonably develop my own projects due to the quantity of errors being output all over.

See the Codex and Theme/Plugin Review for tips and best practices.

define(WP_DEBUG, true);

Please?!?!?!?
Thank you. End gripe ;)
