I notice a bar in my quest log that says "Story Progess with a 1/whatever number. Dependant on the area. The problem is I cannot find any of the quests required to complete the area.
If its in older zones it may be because you are level 70 and have out leveled the quests. Next to your mini map theres a small icon to push if you do so check “trivial quests” and it should pop up quests in the older zones for you.
