tabs not working on menu and lightbox fail

tabs on menu work in the editor, but not on any live browser. Dinner, Drinks, Wine are linked properly in the upfront editor, but dont work on front end, it is just slamming all the menus items together.

also, my gallery was set up as a lightbox and it was working, but now it isnt.

also, the video linked from youtube works some times, but sometimes it doesnt.
