I've just found what the true error is: Wikia have uninstalled the extension globally. It's not listed on Special:Version. It's no bug, it's not going to work again until Wikia reinstall it.

As for the extensions, you're looking at wikimedia's repository, rather than Wikia's. Wikia don't update extensions without extremely good reason unless they're doing a MediaWiki upgrade. We updated to 1.19.3 before DPL was updated (to 2.something iirc), so were not using the latest version anyway. It doesn't help that there's no obvious documentation on what the last update actually did beyond the 2 line description on the extension page.

Extensions are installed, like you might install Photoshop or Norton antivirus onto your computer. If you don't update what you've installed it's going to remain as the older version regardless of what's being released.
