Quote from ixllI am getting this as well with the added effect of breaking my glyphs. My enhanced scorch starts not working after I get this error and works again after I relog. I have recreated this multiple times.
I've had the same problem. I tracked it down to WoW's new built-in threat tooltip system.
You'll need to go into Interface > Display > Display Aggro Warning set to Never.
I've got an issue myself with PitBull, this one is to do with setting a focus. Any time I try to I get this error:
"PitBull has been blocked from an action only available to the Blizzard UI. You can disable this addon or reload the UI."
I did some bughunting with ACP and buggrabber, its definitely PitBull (Only addon that I had running). Buggrabber reports this error:
"1. <event>ADDON_ACTION_BLOCKED:AddON 'PitBull' tried to call the protected function 'FocusUnit()'.
<in C code>: in function 'FocusUnit'
Interface\FrameXML\UnitPopup.lua:1181: in function 'func':
Interface\FameXML\UIDropDownMenu.lua:568: in function 'UIDropDownMenuButton_OnClick':
<string>:"*:OnClick":1:in function <[string "*:OnClick"]:1>"
Seeing the UIDropDownMenu bit I tried /focus. This worked but is there any way to set a focus without having to type in /focus or have yet another button and not get an error?
