These are the most common solutions when the leaderboard isn't working correctly and not showing points:

1. Using the wrong contest slug. There are many different reasons this can happen, but make sure that the contest slug for the contest you are currently running or setting up is the correct one in your leaderboard shortcode. If you have any doubts, go to the Implementation tab for the specific contest and copy and paste the leaderboard shortcode out of there.

2. An incorrectly set up contest link. If your contest link isn't set up correctly (the most common error is using a page or folder that already exists for the link path), then points won't be awarded correctly, or sometimes no points will be awarded at all.

3. On some websites, it is necessary to remove the quotes around the contest slug in order to get the leaderboard to work correctly. For example: [contest_leaders contest=your_contest_slug].
