Flash message detection not displayed

Devise works fine in my application, with the exception of flash messages from devise.en.yml not showing in the view. What am I doing wrong?

Below is my page view up, I tried both :alert, and :notice, but didn’t work.

Thank you in advance

<h2>Sign up</h2>

<% if flash[:alert] %>
  <%=flash[:alert]%>
<%end%>

<%= form_for(resource,:as=>resource_name,:url => registration_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>
  <p><%= f.label :Username %></p>
  <p><%= f.text_field :username %></p>

  <p><%= f.label :email %></p>
  <p><%= f.text_field :email %></p>

  <p><%= f.label :password %></p>
  <p><%= f.password_field :password %></p>

  <p><%= f.label :password_confirmation %></p>
  <p><%= f.password_field :password_confirmation %></p>

  <p><%= f.submit "Sign up" %></p>
<% end %>

<%= render :partial => "devise/shared/links" %>

Did you try to pull flash material? Devise_error_messages should take care of them. Mine works without it, and in the original view it doesn’t: https://github.com/plataformatec/devise/blob/master/app/views/devise/registrations/new.html.erb
