 h3. Changing the default html tag type of the flash elements
 
 As a default the html tag used to wrap the flash messages is a div element.  This can be easily globally changed with the following setting.
 
-<pre># config/initializers/flash_messages_helper_settings.rb
-ActionView::Base.flash_message_tag = :p</pre>
+<pre><code># config/initializers/flash_messages_helper.rb
+FlashMessagesHelper.configure do |config|
+  config.wrapper = :p
+end
+</code></pre>
 
 With the above setting flash messages will be wrapped inside of a paragraph tag rather then a div.
