This week, Wikia changed over from Dynamic page list 1.9 to 2.0. DPL is a little extension that allows us to create simple dynamically-expanded lists. For instance, there's one at United States Marshal, which will increase that list every time a page is added to Category:United States Marshals, thereby keeping that page as up-to-date as possible.
Unfortunately, as we've discovered at w:c:drwho.answers, there are some pretty major syntax differences between 1.9 and 2.0. Things that have been working fine for a while suddenly don't work at all.
I don't expect that many pages here at Tardis might be impacted. But they might be. If you encounter any pages where the DPL lists don't seem to be working, lemme know.
Or, if you're really ambitious and looking for something to do, you could check this list of pages where we use DPL. Then, you could report back here to indicate any problems you've found.
