Devise: not visits the site?

Good time of day.

Put Rails 3.2.13 + Passenger on it — Devise 2.2.4. Settings changed only the mail plus the translated form from erb to slim. Now there is a strange bug: after the registration or password recovery entrance to the site is fine, but to go through the login form does not work:
Started POST "/users/sign_in" for 188.186.102.147 at 2013-07-14 17:58:42 +0400

E-mail and password entered are correct, copy-paste already.

Anybody with such did not face?

Solution
Put Rails 4, and with it this bug does not occur.
