Q. How do I turn on auto-tracking of quests?
A - Look in the options for the game itself, not QuestGuru. Under Objectives there are options to set when to track quests.
QuestGuru does not duplicate these settings in its own options as it could become problematic and it is not necessary to duplicate options already available.
Q. Where can I find a version compatible with WoW patch x?
A. QuestGuru is supported for the current Expansion and Patch level running on the live servers. PTR versions may be supported as Alpha or Beta releases, but I offer no guarantee.
