probably because of the error reported here http://wordpress.org/support/topic/fatal-error-call-to-undefined-function-is_site_admin-2
(just a cross-reference)
see http://codex.wordpress.org/WPMU_Functions/is_site_admin
The function is_site_admin needs to be replace with is_super_admin(). Maybe the plugin developer could take care of this?
