Fatal error: Call to undefined function _fb_menu_title_helper() in C:\xampp\htdocs\drupal\includes\menu.inc on line 504

Hi guys,

After I upgrade from beta7 to beta8, I cannot see drupal site anymore. It shows me:

Fatal error: Call to undefined function _fb_menu_title_helper() in C:\xampp\htdocs\drupal\includes\menu.inc on line 504

I have cleared cache using phpmyadmin; it does not help at all.
