I ws just going to suggest checking the frame fixings to check the
frame is still sitting tight. Go around it with a good spirit leve too.

At a guess -if it's a glass panelled door; I'd say that the glass has
not been fitted properly. It should be resting againsts a packer up
near the top of the side opposite the hinges and a packer on the bottom
near the hinge side.

Similar in principle to the way a brace is inserted in a ledged and
braced door.

As the door opens you will be able to see if I am correct as it has
dropped onto the threshold on the lock edge.

If it is plastic pannelled then they will not be heavy enough to do
that damage. In which case the fitting have probably come loose. You
will have to drill plug ans screw extra fixings in the frame to bring
it back.

Check for dropped packers and make sure it goes back square -there may
be a temptation to over compensate. There might be a measure of "drop"
if you think it need that. Don't forget to re-seal it.
