Blender: Rig breaks

Hi, my blender character is rigged and the rig is already generated, however Im trying to make some small changes. But now, all of a sudden, every bone I move does not affect the movement of the character one bit. However if I go to weight paint mode, all the weight paints are still there. This is the 3rd time it happens, does anyone know why?

maybe the armature is in restpose, should be PosePosition.

or check also this settings of the rigged character

can you post the blenderfile?
but if this happens more often it is stupid and not nice,
