Quests are not working on my character

[Johnbones 0]

My character "Johnbones" on the Anathema server does not get incremented his objective count when killing a quests enemy. It does not work on any quest. I tried deleting the quests and taking them again, and it is still not working. Also tried on many quests and I can't progress on them because of that.

I think the bug started happening when I invited someone to my group while I was killing a quests objective.

Abandon the quests, close WoW, delete the WDB folder and then try again.

That should clear any corrupt quest data... hopefully. Otherwise put in an ingame ticket.
