WotLK My quests map Bug????

[kondoriano]

Hi, I have a problem with this character. while I was checking the map for quests, unfortunatelly i pressed some buttons and all of my quests disappeared. i checked the box show quests objectives, is checked. and the problem is not solved, so i logged out and i deleted folders: cache, interface and wtf. I loged in again and still the same problem. So i tried another character to see if it works and it seems that there is no problem, i can see the quests on map.
I tried on another pc, and i used /reload ui, and still the same problem. What should i do?
