I have been getting messages that you get a wow error on a druid character above level 100+. So this is how you fix it.
1. Go to your WoW folder and look for the WTF folder
2. Go into Accounts and find your character which is a druid.
3. Find "config-cache" and edit it....
4. It should look like this:
SET questLogCollapseFilter "-1"
SET trackedQuests "v"
SET trackedAchievements "v"
SET cameraSavedDistance "5.550000"
SET cameraSavedPitch "-13.742693"
SET playerStatLeftDropdown "Playerstat_base_stats"
SET playerStatRightDropdown "Playerstat_base_stats"
Change "Playerstat_base_stats" to:
Playerstat_melee_combat
5. Save the file with the same name, usually SAVE AS does the trick and u should be set!
6. When you go in-game it should be blank. You can change to anything but. Base Stats!
