Quest helper help

i installed the quest helpr add on and when i log on my quests arnt showin up with ques helper i type /qh hidden and it says unable to complete but the other day they were showin up on my map anyone know the problem?

Sometimes it glitches up. I have had this problem before, it will show it one time on the map, then I look at the same map a day later and everything is gone. Sometimes if you wait 10-15 min it starts appearing. Must be a minor glitch. If thats not the case for you. See if the quests you have are even in the QuestHelper database.

i found that light headed mod helps amazingly with quests, from coords to minimap icons and tips from other gamers the link is below
