navbar drop down menus not working

[dr_way]

i recently edited my navabar aswell as some other areas of my forums and now ive noticed that the drop down menus on the search and quick links functions arent working. the arrows arent even producing a pointer on mouse over.

any idea what needs to be rectified to fix this?

im using 3.0.6
