Javascript error on buddypress website

I have a buddypress site that has been running fine for months, but this week I checked it and suddenly none of the animation or javascript popups are working. I haven't made any changes to the files to cause this. Any help or insight you can give to help me resolve this issue quickly is greatly appreciated. The site is throwing the same error twice:
Uncaught TypeError: Object [object Object] has no method 'live'

Appreciate the help!
