Why isnt my rig following my character?

I have rigged my character and everything is working fine. I can change the rig in pose mode and my character moves pretty fine. But when I move my character in object mode my rig isnt moving at all. I cant parent it again, so can anyone tell me what to do?

Don’t move your character mesh once you’ve rigged it. Create and use a root or main bone instead whose sole purpose is to move the rig and mesh in alignment.
