Tried a different method to connect to Google but it seems it didn't work. I sent a message to our host already.
UPDATE: So... it's fixed.. apparently, XD . Honestly, it is quite odd since the fix was on a file that is not even being loaded at all. I mean.. it doesn't even exist on the directory where the Smash and the Splatoon cards are, it's a left over file that only exists in the Mario Kart 8 cards directory.
