In order to place a Wordpress site in debug mode add the following 2 lines to the config file of your Wordpress site. The config file can be edited from both the Control HQ and the Hub using the file editor.

define('WP_DISABLE_FATAL_ERROR_HANDLER', true);   
define('WP_DEBUG', true);

|| Placing your site in debug mode will degrade performance, so be sure to disable it when you are finished.
