Umm... The boot log says you're on Hijack v312, and the khttpd_root_index option wasn't added until v313. I don't know if that throws off config.ini parsing or what, but certainly, it's a good idea to either upgrade to Hijack v320 or take that option out.. Otherwise, your syntax looks right and we should at least be getting an error if something else is wrong, like permission or filename errors.
