Thanks for the reply. I found out the problem. I had a Sort by "DocumentLastPublished DESC" on the SmartSearchResults repeater that was breaking it. It worked before, and I don't know why it would be the cause.
I had initially wanted to sort by "DocumentModifiedWhen" but it wouldn't for some reason. I could sort by any other field but this one, so that's why I settled on "DocumentLastPublished".
I need to do a little more digging.
