WowAce

Though I certainly don't know for sure, I assumed that all data is more or less plain quests, as they can be datamined, but then the details are filled out when people contribute data with the Wowhead Client.

As you can see, there isn't much I can do about sorting which quest is for which class if Wowhead does not have the information. Some quests here are also listed as requiring other Alliance races, despite the fact that it is the human starting zone. There are also a good handful of quests here that have more than one starting point, which unfortunately must be ignored because I have no way of figuring out which is the right start point. If you have a specific quest that still does follow what I've said here but shouldn't be showing, let me know which.

Edit: And I just realized the class-specific quests were not on this list, but you can find them in step 4 of the quest chain here. If you click on each one, you will note that there is no class requirement listed. Interestingly enough, looking at the entire list of mage quests (as well as each Human-available class), you will note that there is exactly one quest in each that is not labeled properly, and that is the one that starts in Elwynn Forest.

pdb: Do me a favor, and update to the latest revision (r35). This will likely not fix your problem, but after about a minute or two of being logged in, type /qhub and tell me what it outputs. This way, we will be able to see if the problem lies in getting information from the server or not.

pdb: If you reload your user interface or log in at a later time, do these quests still show? Also, are you using the enUS client? If not, which? As for the missing quests, there isn't much I can do without Wowhead updating or getting user submitted data. I am frequently checking and getting new data, so hopefully I can have those quests soon.

Did you make sure you completely exited out of the game and restarted after you installed the addon? If you installed those parts separately but forgot to do that step, they would not be loaded.

And, just to confirm, you can see quests in other zones, correct? It's just those two continents that you are having trouble with?
