⚠️ Due to the nature of taint, errors can easily be blamed by the client on the wrong addon. When running multiple ones, it is generally not clear which caused the issue. Tracking down the cause can also be complicated.

Which software were you running?

• Addon version: 11.0.1
• Client used: Retail 11.0.2.56162
  Please describe how to reproduce it.
  Steps to reproduce the behavior:

1. Accept a quest which requires using an item
2. Click on that item from the quest tracker

1x [ADDON_ACTION_FORBIDDEN] AddOn 'PetTracker' tried to call the protected function 'UseQuestLogSpecialItem()'.
[string "@!BugGrabber/BugGrabber.lua"]:485: in function <!BugGrabber/BugGrabber.lua:485>
[string "=[C]"]: in function `UseQuestLogSpecialItem'
[string "@Blizzard_ObjectiveTracker/Blizzard_ObjectiveTrackerShared.lua"]:94: in function <...ObjectiveTracker/Blizzard_ObjectiveTrackerShared.lua:87>

Locals:
_ = Frame {
}
event = "ADDON_ACTION_FORBIDDEN"
events =

Have you tried disabling all other addons and verified the problem remains?
No. But disabling Pet Tracker fixes the issue.

Here is the taint log:

8/20 05:49:32.631 Interface/AddOns/Blizzard_ObjectiveTracker/Blizzard_ObjectiveTrackerShared.lua:94
8/20 05:49:32.631 An action was blocked because of taint from PetTracker - UseQuestLogSpecialItem()
8/20 05:49:32.631 Interface/AddOns/Blizzard_ObjectiveTracker/Blizzard_ObjectiveTrackerShared.lua:94

Same, disabling PetTracker solves the issue

I'm having the same issue, ended up disabling pettracker as well.
I noticed it is also missing data for the war within.
I have switched to another addon called battle pet completionlist, which doesn't have these errors, and already have the war within pets on the map.

I am experiencing this as well.

1x [ADDON_ACTION_FORBIDDEN] AddOn 'PetTracker' tried to call the protected function 'UseQuestLogSpecialItem()'.
[string "@!BugGrabber/BugGrabber.lua"]:485: in function <!BugGrabber/BugGrabber.lua:485>
[string "=[C]"]: in function `UseQuestLogSpecialItem'
[string "@Blizzard_ObjectiveTracker/Blizzard_ObjectiveTrackerShared.lua"]:94: in function <...ObjectiveTracker/Blizzard_ObjectiveTrackerShared.lua:87>

Locals:
_ = Frame {
}
event = "ADDON_ACTION_FORBIDDEN"

Yeah same problem here. Guess I'll disable the addon until this gets fixed.

Error doesn't happen after disabling PetTracker. Might be a taint issue but it does seem to be the cause here.

Same issue here, I had to disable the addon:

2x [ADDON_ACTION_FORBIDDEN] AddOn 'PetTracker' tried to call the protected function 'UseQuestLogSpecialItem()'.
[string "@!BugGrabber/BugGrabber.lua"]:485: in function <!BugGrabber/BugGrabber.lua:485>
[string "=[C]"]: in function `UseQuestLogSpecialItem'
[string "@Blizzard_ObjectiveTracker/Blizzard_ObjectiveTrackerShared.lua"]:94: in function <...ObjectiveTracker/Blizzard_ObjectiveTrackerShared.lua:87>

Locals:
_ = Frame {
}
event = "ADDON_ACTION_FORBIDDEN"
events =

I am also having the issue
