Reply To: function

Yesterday I had already written in easyreservations.php :
define(‘RESERVATIONS_DIR’, WP_PLUGIN_DIR.’/easyreservations1/’);
define(‘RESERVATIONS_URL’, WP_PLUGIN_URL.’/easyreservations1/’);
But I work for everything except for “print the invoice” after the click path is always this :
wp-content/plugins/easyreservations/lib/modules/invoice/editor.php?id=
But I want that focuses on :
wp-content/plugins/easyreservations1/lib/modules/invoice/editor.php?id=
Is there any setting regarding the invoice to change?
