Devise not saving encrypted_password

[paulo....@chefsclub.com.br]

Hi, Guys!

Just installed latest Devise version on my 4.2.0 rails application.

After signing up, I was correctly redirected to the admin route.

When I logout, I return to the sign in page. So far, so good.

When I try to sign in again, it doesn't work. After investigating for a while, I realized that my user on the User table has the encrypted_password field empty.

I am completely stuck on it. Any ideas?

Att,

Paulo
