PHP constants don’t have the leading $. Strictly, this isn’t WordPress, but since there isn’t a Core is_debug() function that I am aware of, what you want is: if (defined(‘WP_DEBUG’) && true === WP_DEBUG) { echo ‘d00d’; }
When WP_DEBUG is set, WordPress sets (via wp_debug_mode() call early in core load process) the error reporting level to E_ALL & ~E_DEPRECATED & ~E_STRICT. This means all warnings and errors except strict errors and PHP deprecated functions (not WordPress ones). You can define your own level in a custom mu-plugin (the override needs to be … Read more
There is an easy solution with a Firebox extension Xdebug Helper by Brian Gilbert. This sets cookies for the xdebug session which allows you to use xdebug within your WordPress plugins. There are also extensions for Chrome, Safari and Opera. The links can be found on the xdebug website
I ran into that issue too, and it turns out that it was because there actually was an error that wasn’t displaying. Once I fixed that underlying error, the top margin problem went away.

admin-ajax.php loads wp-load.php: /** Load WordPress Bootstrap */ require_once( dirname( dirname( __FILE__ ) ) . ‘/wp-load.php’ ); wp-load.php loads wp-config.php, and there wp-settings.php is loaded. And here we find this: // Load the functions for the active theme, for both parent and child theme if applicable. if ( ! defined( ‘WP_INSTALLING’ ) || ‘wp-activate.php’ === … Read more

If you just want to have it changed within wp-config.php you can replace define( ‘WP_DEBUG_LOG’, true ); … Read more
