devise reset token

The link should be generated with:

edit_password_url(@resource, :reset_password_token => @token)

If your view still uses this code, that will be the cause of the issue:

edit_password_url(@resource, :reset_password_token => @resource.password_reset_token)

Devise started storing hashes of the token, so the email needs to create the link using the real token (@token) rather than the hashed value stored in the database.
