Opened door to let mum in and it suddenly won't close! What on earth has happened?!?

Question

Let mum in after walking the dog and now the door seems to overlap the frame considerably. It won't close at all!

It's sunday and we have no idea what to do. There is nothing obstructing the hinges we have checked everything

Is it even possible that it could've expanded that quickly?!

Answer 1

Check if the pins are in the hinges, or if the screws have come loose.

Answer 2

If the door is overlapping on the lock side of door,check the hinges  get a block of timber and a hammer hit it where the pins are back toward the hinge side of door frame,check your other door hinges so you get an idea of what to look for,if you've bent the hinges you;ll, need to replace them,doors just dont sh*t them selves all of a sudden unless its been slammed,cant say much more without seeing it
