Error occured in: AddOn: <xxx>

Message: Error: AddOn <xxx> attempted to call a forbidden function (FocusUnit()) from a tainted execution path.
Debug:
   [C]: FocusUnit()
   ..\FrameXML\UnitPopup.lua:1877: func()
   ..\FrameXML\UIDropDownMenu.lua:748: UIDropDownMenuButton_OnClick()
   [string "*:OnClick"]:1:
      [string "*:OnClick"]:1

I used <xxx> as the AddOn because no matter WHAT addon i enable/disable I get this message.

There is an addon that taints the default Blizzard UI.

Disable all addons, then enable them one by one, do with every newly enabled addon what you're doing to get the error message, and see which addon is the guilty one.

Oh, and you could do full text search in your addons folder for "UIDropDownMenu". Every addon that contains this string could be the cause.

It seems all of my addons minus Stuf Unit Frames is causing this error. All I'm trying to do is set a focus.

*shrug*

A list of the said addons could be helpful.

This has been an issue for years. Only the default UI's UnitFrames can get away with using SetFocus() in their dropdown menus.

Here are some (of many) examples of people talking about this:
A WoWI forum thread from 2010: http://www.wowinterface.com/forums/s...ad.php?t=29869
An X-Perl ticket from 2009: http://www.wowace.com/addons/xperl/t...s-not-working/

We used to have to remove the Set Focus option from the unitframe dropdowns until they gave us the ability to set the dropdown securely though :SetAttribute('type2', 'togglemenu').

Without a list of your addons there's just no possible way we can even guess which addon might be causing the problem.

Here's the easiest way to get a postable list of your addons:

Open your AddOns folder in Windows Explorer. Shift-right-click on a blank space in the window. Click "Open command window here" in the popup menu. Type the following command and press Enter:

@dir /on /ad /b > addonlist.txt

(Note: The command window doesn't support pasting with Ctrl+V, but you can paste by right-clicking and selecting "Paste" in the popup menu.)

Now, open the new "addonlist.txt" file in your AddOns folder and copy/paste its contents into a post, or just attach the file itself to your post.

Or you could post the contents of
<wow folder>\WTF\Account\<ACCOUNTNAME>\<ServerName>\<CharacterName>\AddOns.txt

[Phanx]

Does that actually include all the addons now, or just the ones whose enabled states you've ever changed?

That list isn't good, as it includes addons that have been deleted long ago, and it's not sorted alphabetically either.

After further research I found that it also includes addons I never had. Apparently, if any other addon is being referenced somewhere in your addons, it will be listed there, regardless whether you have it or not.
