Since this is almost certainly custom Wikia code and not standard MediaWiki stuff available outside Wikia, your best bet for an answer is Special:Contact. Anyone else would likely be guessing or doing potentially faulty reverse-engineering.

Of course, if someone figures out a hidden parameter and how to pass it to the code that works, you could just use that until it breaks.
