I don't understand. If so, it should have been made so that badge would not be shown at all without an add-on. In addition, as you can see in the screen shot, it said "This code will integrate MyCred User Ranks and Badges under comment author avatar."
And I'm thinking about buying that add-on. But, there's an error like this. I am worrying about that the same error will occur if i purchase add-on.
