Thread Auto-Load Not Working

@admin staff @TWIN GALAXIES

Ever since the recent site update, I've noticed that multi-page threads no longer auto-load the next page of posts. It still works for blogs but seems to be broken for the forums in general. Attached is a picture of what I'm talking about (taken from scrolling to the bottom of current blog comments):

The same functionality used to exist for scrolling through forum posts, so I was hoping you guys could hook it back up.

FYI - I'm using Google Chrome (and yes, I cleared my cache beforehand).
