Waf-fle login authentication issue

[PrimeFlix-Status]

Once I finish my waf-fle setup. I can't log in into the portal. which is http://xx.xx.com/waf-fle/login.php
it always says "Invalid Username or Password" how many times you entered. It only allows when you set up then once you sign out you can't login again.

Pls if anyone finds a solution for this let me know here.

I'm implementing on google cloud Debian.

stored crypt password is not the same as entered sha1 password. If I store the entered sha1 password by echo, login works.
