Unable to talk to the Scryers

I have a draenei DK on lordaeron server, with which I've got 250 reputation with the scryers, however I am unable to talk to them, they are, along with the aldor "at war", and I cannot remove the checkbox. The first day that I've gotten to neutral with the scryers I was able to learn some profession skills from the cryers, but after going offline I cannot talk to either faction. How can I fix that?

Note: I did not complete the City of Light quest yet (or don't recall doing so), and Khadgar doesn't have it.
