Update: There's an issue with the way I remotely authenticate and access the server. I messaged @Nayleen and as soon as we get that resolved, I'll get themes and all forums software updated and, hopefully, "fixed."
PSA: Rooke's Crappy Default Theme MAY be the "best working" theme at the moment, but it's gauche and sucks. It's not worth it. Do not listen to Rooke.
