With the recent bugs with the menu options with Questing, I would recommend two addons. These addons will solve the issue with questing temporarly, also I would make sure you download a custom combat routine for your class and config that. Improved Nav Plugin and I want movement. The addons are called;
Turn in;
Turn In - Quests & Leveling - World of Warcraft Addons - Curse
and Turn in Everything;
TurnInEverything - Quests & Leveling - World of Warcraft Addons - Curse
These two are the best and will pick up/turn in any quest you click on. You have to go ingame and type /ti on, which will turn it on. Then type /ti help for more commands. Cheers!
