For those that wanted a pre-made leaderboard, here is one I made:

http://s000.tinyupload.com/index.php?file_id=72443483567597873242

The leaderboard shows 10 players at a time. You can go to next / prev 10 players. There's also a button to view the top 10 players, and button to view your position in the leaderboard.

It shows Player rank, score, name, and image.

I can't give much support, but feel free to use it.

To test it, just change the name of the leaderboard (mine is non-contextual), and upload the export to facebook, all submitted scores will show up. (note: I've only tested with a few players in the leaderboard)

Hey jagoman, I opened your solution link but sadly the file is missing from there. Can you re-share it please, that would be a huge help cause it has the solutions for all the problems and unknown i am facing right now with the FB instant leaderboards.

Thanks.

Hey fellow devs, I am in process of releasing my first game on facebook instant but I am heavily stuck on leaderboards. I have read the whole tread, tried some posted solutions but it still dosent seem to work, I saw some solution links posted but they are all empty now. So please if someone has already successfully implemented the leaderboards in fb instant, kindy share your solution/ events, regarding getting the images of players, names and score.

It would be a great help to us and we will be more then gratefull for that. I am stuck on this thing for past 3 days, i am willing to share my code if needed.

HELP!

Thank you Zenox98 for quickly coming to my help! I get the part where i have to remove cf_not_invertible, however I am unclear about where to remove it from. Could you kindly clarify this issue? Thanks!

Hello Vinterstille,
