I've been getting this error any time I am targeting a player character. It continually pops up. Also, inspect works about 1/4th the time I try it.

Message: ...\AddOns\Blizzard_InspectUI\InspectPaperDollFrame.lua:23: Usage: UnitLevel("unit")

I have attempted deleting the Blizzard_InspectUI folder so WoW can rebuild it, but I get the same error.
