Side Bar Misplaced

Just recently, my sidebar has changed from being at the side (right-hand side) of the page to being at the bottom the page – and not as a footer, but rather just as a long, misplaced “side” bar. The footer is at the right side where my sidebar was.means my sidebar misplaced from right side and goes down
