conversion from Sqlite3 to MySQL

[ZAJDAN]

Hello,
on Sqlite3 Devise worked without problem.
Now I converted db from Sqlite3 to MySQL and Rails returns error:
Mysql2::Error: Unknown column 'users.' in 'where clause': SELECT users.* FROM usersWHEREusers.`` = 1 LIMIT 1
in my Table is not column 'users'...I have just:
id, email, encrypted_password, reset_password_token, reset_password_sent_at, remember_created_at, sign_in_count, current_sign_in_at, last_sign_in_at, current_sign_in_ip, last_sign_in_ip, created_at, updated_at

is necessary do something more after such conversion database?

Thank You
