WotLK World quests not showing on my map

[endmymymylife]

Hi so recently I made up a new character and when I got to the lvl 17 my quests just vanished from my world map, at first when I log in with my character they appear but when I close and open the world map again they're gone, then I thought its maybe just a glitch on this character, but the next day I made a second character (same race and class) and the same problem

Anyone had this problem that can share their solution on it?

That happens if your quest log is full. Abandon at least one quest.
