Since last Thursday's undocumented update, all site builder sites that I've tested are failing to return ANY content when using a single-digit query string parameter. Examples: https://www.georgesmusic.com/?q=43w432 https://tdr.fourthwc.net/?d=342 http://pupgearpetproducts.com/?q=dog I know search spring and probably other 3rd parties rely on those query strings for their implementation. I have a case open with NetSuite but they are still looking into it.
