Quests disappear from the map (WOTLK, Lordaeron)

My quests disappear from the map, only one is shown and it is on the wrong locaion. When I /reload they all appear again, but then they are gone again when I re-open the map. Though, when I write /reload they seem to mark the wrong places of the map. Quests and maps works perfectly on other toons, on both Ragnaros and Lordaeron.

Basically, the quests are gone from the map.

Server: Lordaeron
Character name: Olov

My troubleshooting:
Restarted computer and game
Deleted WTF-folder
Brought back my old WTF-folder
Deleted one quest (I got 4 quest, so it's not full)


Thanks in advance!

Does anyone know?

Pretty much the same issue here, no quests are shown on my map, none at all.

Server: Lordaeron
Character name: Lanoroth

My troubleshooting:
Resterted the game
Deleted Cache and WTF folders
