According to the documentation cited below I should be able to add a path to save the debug.log at but it does not seem to be working for me.

define( 'WP_DEBUG_LOG', '/tmp/wp-errors.log' );

in wp-config.php I have:

define('WP_DEBUG', true);
define( 'WP_DEBUG_LOG', '/tmp/wp-errors.log' );
define( 'WP_DEBUG_DISPLAY', false );

The log keeps saving to the default location instead. Any help as too why this would not behave as expected is appreciated.
