Welcome to Echoes of Doom!

Patch 3.0.2 saw significant changes to many parts of the UI and its API, and along with these changes we have new possibilities for taint. If you get a message that states an "Interface action failed because of an AddOn", it means that an AddOn interfered with the Blizzard UI in some way.

Please check for updated addons - the problem you experienced may already have been solved!

If the problem still happens after updating your addons, you can diagnose what's going on and let the author know:

To diagnose this, enter the following into chat "/console taintLog 1" and restart the game and try to reproduce it. If you reproduce it, you can quit the game and search through the file Logs\taint.log for the word "blocked". Once you have done this you can turn off logging by entering the following into chat "/console taintLog 0".

Please use this thread to post links to your taint.log file if you get this message.

You'll only get the "blocked" messages in combat, so the easiest way to test this is to go to a low level zone and let a weak creature attack you while you do things involving targeting, group changes, pet changes, etc.

Remember, taint by itself is fine, it only becomes a problem if it results in a "blocked" message.

Thanks!

Fixed for 3.0.8

• Addons that use the built-in UIDropDownMenu system should no longer cause Focus related options in Unit DropDowns to stop functioning.


• QuestLogFrame replacements should no longer interfere with SpellBookFrame_OnHide


• Many overachieving variables are not quite as global as they used to be, including:
  
  • self - Blizzard_RaidUI.xml line 1222
    
  • powerTypeString - Blizzard_CombatLog.lua line 3046
    
  • frame - ContainerFrame.lua line 95
    
  • enabled - BonusActionBarFrame.lua line 284
    
  • point - Blizzard_CombatLog.lua line 3440
    
  • finaloffset - MainMenuBar.lua line 20 etc.
  
  

Known Issues

• Successive calls to OpenCalendarEvent result in Interface Action Blocked messages.

Thanks for the great information so far, everyone!

We're looking into the SecureHeader and OpenCalendarEvent reports, and the issues with variable scoping, SpellBookFrame_OnHide, and UIDropDownMenu should all be fixed for 3.0.8.

Hey Tuhljin, thanks for the reports, these are fixed for 3.0.8 as well.
