Yes, it's the DPL. "Dynamic Page List" is a kind of an 'app' that allows us to dynamically make lists like that one. Either the app was updated, and the query needs to be rewritten (on Template:Chronological_Sort) or some wiki code was updated that broke the DPL use. Since we're still getting a list, I'm inclined to believe the former.

I'll poke at it and see if I can fix it on my own quickly, and use Special:Contact to see if Wikia can help us if I can't get it back myself.
