menu’s / forum sidebars / login overlay problems :(

A few things,

1. The login/new user button when pressed just comes up with the overlay to login but no login window, and then when you click out of that, none of the site menus work, you basically can’t click anywhere just Refresh.

2. Also non of the drop down menus work.

3. can’t seem to add a side bar widget to the forum page 

thanks
