Phpass problem

Hello everyone.

I’m encrypting passwords using phpass ( ). Anything working correct.
I got problem when I uploaded website to server. When user typing password, I’m checking with stored password from database, it’s returning false.
But in my local server, it’s working fine. I have uploaded webisite to another server to check, and in this server it’s working ok too.
Why I may have this problem in that server?

Carefully compare the output of


from each server.
