my Ui, as you can see, is completely messed up, and I dont know how to put these things back to their formal place.

can someone help please?

try disabling your addons, as one of them is likely the cause. if it goes back to normal after disabling them, re enable them 1 by 1 till you figure out which one is causing it.
