Cant get into AC

So i just started playing i am level 21 and i cant open AC. When click on the AC guy nothing pops up. Anyone know why? :)

What do you mean by AC?

oh sorry i meant AH - Auction house. I'm dumb

Be sure you are interacting with the correct NPC's, and right click them. If you still have issues, I would suggest try turning off your addons.

I click on the right ones and still have the issues
