If you don't have Raid Frames for your layout ...

do -- fix SET_FOCUS & CLEAR_FOCUS errors
    for k,v in pairs(UnitPopupMenus) do
        if k ~= "RAID" and k ~= "RAID_PLAYER" then
            for x,y in pairs(UnitPopupMenus[k]) do
                if y == "SET_FOCUS" then
                    table.remove(UnitPopupMenus[k],x)
                elseif y == "CLEAR_FOCUS" then
                    table.remove(UnitPopupMenus[k],x)
                end
            end
        end
    end
