You can’t reactivate a Leaderboard, but you can clone one to create an exact copy of the Leaderboard.
- Simply go to the leaderboards page
- Click the cog icon at the end of the row for the leaderboard you would like to reactivate
- Click "Clone"
- Then you only need to set the start and end date. You can also change other settings or add/remove participants if you would like.
- Then click "Create Leaderboard" and your done!
