No Vendors / NPCs in OG

I still dont have any vendors in OG, somebody told me its because of some chain Q i did in NR. Everytime i send a ticket, GM told me to say about it more detailed.... Its only on this character, where i did most of Northrend quests. I dont have any active quest now. Now all i have in OG is this (via screenshot).

You're in the middle of the Wrathgate quest line. Walk over to Thrall and accept the quest he has there, take the portal to UC that spawns in the throne room and do that sequence.

Thx man, you were right. I did Wrathgate achi 3years ago but didnt finish Step 7: The Betrayal.
