Maps not displaying quests

[Andy3112]

i have had 4.033 installed or a while now with no issues. but just suddenly the maps no longer display any quest information that i need. all i can see is the map itself and the '?' to hand in quests. there is no longer any '!' to collect quests or quest areas colour marked. I have no other addons running. This literally happened between logins. one moment its working then suddenly nothing. its the same for all my characters on all the realms

any ideas?
