I am pretty certain, achievements are enabled in settings.
Yet, when clicking on a members profile <achievement link> it doesn't show member achievements.
It will take you to the link that it should display; such as http://www.website.com/member-id/badges/achievements

Instead, it will show the member's who is searching the other member's achievements, achievements.
So if Penelope is searching another members achievements, it will show Penelope's on the other user's url.
