The Mail template defined in index.php ($file['default_mail']) or in <input type="hidden" name="mail_template" value="" /> does not exist. Please make sure the file name is spelled correctly and the file is available in the template directory.
Note: Once the script configuration have been finished you can set off these system messages (index.php - $show_error_messages).
