Introduction
When facing issues on a Wordpress site, it may be helpful to enable debug mode. This will provide more verbose logging.
Procedure
In the "wp-config.php" file within your WordPress installation directory, find the following lines:
define('WP_DEBUG', false);
define('WP_DEBUG_DISPLAY', false);
Alter them to be "true" as in the examples below:
define('WP_DEBUG', true);
define('WP_DEBUG_DISPLAY', true);
