Death Knight start problem.

Hello.
To start im new to wow this is my first ever game within wow so sorry for the faultys.


So i had a mission to go to the basement to kill someone and takes his head. Didnt knew that after some research.
So i went to look for his head now where to be found.
So i abandoned the mission to redo it, but now im stuck there without any numbers or ! or ? its completely empty.
What should i do now?

Now i created another character. Now it seems to be that the teleporten is not even working at all. So im stuck at the very beginning.

The actualy *uhum sorry* ****??????

Death Knight starting zone is pretty buggy at the beggining, it's easy to get stuck, i had to do it two times in order to get out of there, just keep trying. The teleporter takes a moment to work
