-------------------------------------+------------------------------
 When the WP_DEBUG constant is set, calling get_metadata() in /wp-
 includes/meta.php with $single==true can cause "undefined index" notices
 when the meta data value is an empty array. As null is an acceptable
 return value for this function, silencing the notice with @ will remove
 noise when debugging without the overhead of checking the array length or
 that the 0 index isset().
