a great way to safely view error messages when your WordPress whitescreens

wp-debug-safe.php

<?php // do not add this line to your file when copying!
// add this to your wp-config.php file
// navigate to the whitescreen page and add ?debug=debug to the url
// eg: http://mywebsite.com/problempage?debug=debug
// or on a page with query string variables already http://mywebsite.com/problempage?variable=123&debug=debug
if ( isset( $_GET['debug'] ) && 'debug' == $_GET['debug'] ) {
	define( 'WP_DEBUG', true );
	define( 'WP_DEBUG_DISPLAY', true );
	define( 'SCRIPT_DEBUG', true );
}
