WoW character stuck and can't move, how do i fix it

try the cheap stuff first. log out fully and back in, then /reload. if you're wedged in terrain, a hearthstone or any teleport usually pops you out. if you can't even get the character to load, blizzard has a character unstuck tool on their support site. you pick the character and it moves them to a safe spot. had to use it once after logging out inside a wall and it sorted it in a couple of minutes.
