Load Newest – Undefined

On my website I have bbpress and the activity stream set up. I bought a new theme and it’s been great. Except when a user is on the activity stream and the load newest button would appear all it shows is

‘undefined’

I contacted the theme support, and he says it’s not on his end. Because it doesn’t show on his barebones test site. I tried a wordpress base theme, and this error was gone. Tried disabling all my plugins and went back to his theme. It was still there.

Anyone have any advice how to go solve this? Or any ideas to do so? I know you can’t solve it directly because it’s on a theme that’s not basic, but… advice is welcome.
