Ultimate Facebook login, like/send button, fb comments, autopost don't work

Hi, I am having many issues with ultimate facebook plugin installed on multisite MU Blog, wordpress 3.2.1
http://kenyadevconsortium.org/
http://kenyapyla.org/

1. Login doesn't work (button dead), while registration works
2. Like/send buttons not showing
3. Comments do not show on wall of user--Registration not showing on fb wall of user--only if they change their location--then this automatically changes the user's facebook profile and a posting feed appears on their facebook profile-about the change of location -but not about the fact that they registered or made comment on the Website or wrote a blog post.
4. Autopost not working even after Clicking the Grant Permission numerous times. The only thing working regarding Ultimate Facebook is the registration--nothing else.
