After the update, map overlay no longer displays the map. The current area name will show in the proper place but the map itself isn’t there. Attempting to change the map to mini map from full screen crashes the game, this bug is repeatable.
EDIT: clean install has resolved this issue
I have exactly the same problem!
I have the same problem here!
I’m too. I cant turn it on
I have the same thing going on
Same issue here, although i have reinstalled. The error is still there.
same problem here … 
Repair doesn’t work?
My map was working, I reinstalled the game and now it doesn’t work. I tried repairing it and nothing…
I reinstalled it a second time, in a different folder, and the map worked.
Same here.
Fullscreen map isn’t showing.
Game crashes when I change option to display the map on the left or the right corner…
Same issue here - I tried “scan and repair,” which did not find any errors - I then uninstalled/reinstalled, same issue persists. Map will NOT show at all even when adjusting all settings (tabbing multiple times to re-center, etc. etc.). Not finding any help from Blizzard online from this - also, I noticed on another forum that others experiencing the same thing see characters with white hair or fur showing hair and fur extremely bright white. Can’t find any answers/resources online, hoping there is an easy fix or update coming.
Fully delete game and reinstal is resolve this problem .
