I'm not sure. As long as &lt;forum> is listed under Parser extension tags at Special:Version (it comes from the DPLForum extension), you should expect &lt;forum> to continue to work. It's possible that Wikia made some sort update that messed up the extension or how it loads. I know they've been having issues with DPL for a long time, and DPLForum uses a subset of DPL. Sounds like you should report this to Special:Contact/bug.
