This script is a quick fix I made to the original Wanikani Leaderboard script (see [Userscript] Wanikani Leaderboard).
You can get the fixed script here at Wanikani Leaderboard 2
Hope this helps anyone using the old leaderboard script!
If you want more features please request them, I’ll try to add them if I can!
Thank you so much! I was also planning to look into fixing it but never got around to it. I tried this and it works perfectly 
Thank you so much for the quick fix!
I don’t know if this an issue on my end but a couple of days ago the leaderboard started being unable to find any of the users. The entire leaderboard is red, all users (including myself) are displayed like this:
Refreshing does not help, as I said it has been like this for a couple of days already.
It looks like the latest update broke the userscript 
Should I hope the authors will fix it?
The issue with the icons for the leaderboard not showing up has now been fixed (thanks to a friend)! The latest update should be at the same link.
