Z became Y

Hello. i had a few problems and thought it had to do with the parrenting so i just worked my way around it, making everything harder, but i just now noticed that the Z and Y axses has swapped … i deleted the Y azses cause i wanted the character to move smoothly across the Y, but then the Z animation got deleted… so i tried to figue out and found that when i moved the Y Bone Scale the bone went UP instead. i know you can swap Y and Z somewhere, but where is it? dont remember. thank you.

If you post your problem file, I’m sure someone will be able to advise you.
