I turned all addons except LUI and oQueue off and no longer get it, but also don't get it when i turn them all back on.

I have got that same error a couple times and the only addons we have in common is Altoholic. You can try disabling as the author hasn't updated it in a while.

As further info in the quest to resolve this, these are my addons I have installed:

Problem with 1.8.2d...again.

When I inspect someone else, all item level show up as xxx and this is my error. I've tried reloading and it does this every time.

Hope this helps to fix some problems, Tiny.

That update seems to have fixed it, ty. I also deleted the SavedVariables to make sure so that might've helped with the fix.

It happens every time, no matter the character I'm on. I use LUI so I don't know if it's a conflict or not.
