As mega said you need to add all users to a sorted set called users:reputation.
So go through all your users and add their user ids to users:reputation with the score being their reputation.
I tried to install it, and edit below file as the guidline
But, I see that user's point alway show zero and when I had accessed to url
I show as below picture
Pls show me what I can do to resolve this issue.
If reputation isn't increasing that's one issue, but if it's always showing the users as a guest, that's a different issue. "Guest" users will not get reputation because there's no user account.
