Resolved permalinks.php problem

Hi guys. Can anyone shed some light on this file for me. I'm trying to build a web site using WordPress. I've got a fatal error:
Ignore the smilley face.

Fatal error: Call to undefined method suwp:ermalink_mode() in C:\xampp\htdocs\pmgevents.com\wp-content\plugins\seo-ultimate\modules\permalinks\permalinks.php on line 18
