Is anyone else getting a problem starting quest message when attempting to do quests? I just started doing this a few minutes ago for me.

I just finished my Wizard quests (the last ones I have for now) and didn't have any problems. Have you tried going back to the quest page through the widget (or whatever link you use) and trying over? Which quest is giving you an error?
~ I was in the middle of doing Carl's quests and it all of a sudden gave me that error. I tried a different person, Cynthia, was able to do one quest and then got the same error message. I stopped questing for a bit, then tried again and now it's working fine.
