you need to make sure that all the allen keys screws in the hinges are tight, their should be allen key ajuster screw that moves the door in and across the frame, but if the door has dropped you need help to lift and hold the door up wile you tighten the hinge screws, do the unscrewing and tighten on the screws at the (door frame )side of the hinge
