Rails 3 & Devise: Error when logout-Collection of common programming errors

Problem solved

klaustopher his answer fixed the problem.

The problem is that i can’t logout when i have or in my layouts/application.html.erb

When i delete this line out of my application.html.erb, i am able to logout without errors. I’ve searched on google but could not find anything about this problem.

My application.html.erb:

     "all" %>
    
    
    
    
    




  


    

• current_page?(home_index_path) ? "current" : "" %>
• 'bednav' %>
• 'contanav' %>
• 'contrnav' %>
• 'formnav' %>
• • :delete %>

   
  




Inlogd als: 



  
    
     "flash_#{name}" %>
