                      :small => "100x100#",
                      :medium => "150x150>"
                    },
                    :default => :thumb,
                    :url => "/users/user_avatar/:attachment/:id/:style/:basename.:extension",  
                    :path => ":profitnext/public/images/users/user_avatar/:attachment/:id/:style/:basename.:extension"  

# avatar validations
  validates_attachment_size :avatar, :less_than => 5.megabytes
  validates_attachment_content_type :avatar, :content_type => ['image/jpeg', 'image/png'] 
end

and My View:

<%= image_tag @user.avatar.url %>
              <%= image_tag @user.avatar.url(:thumb) %>

I got that error after hitting save button.I am struggling with this a lot.Thanks in advance.

My guess is that this is nothing to do with paperclip but is more along the lines of this. Do you have a has_many :usernotes in your User model and/or a belongs_to :user in your Usernote model?
