   If you're not using your browser's latest version, WP 3.2+ will show you a special notice in the dashboard. This is fine, but in some cases you may want to hide it (i.e. in a client's website). This is how you do it (paste it in a plugin or in your theme's functions.php file):

   function remove_browse_happy() {
      global $wp_meta_boxes;
      unset($wp_meta_boxes['dashboard']['normal']['high']['dashboard_browser_nag']);
   }
   add_action('wp_dashboard_setup', 'remove_browse_happy');

   You can also remove more dashboard widgets this way. If you don't have enough data to use the unset function, you can try with remove_meta_box:

   function remove_dashboard_widgets() {
      global $wp_meta_boxes;
      unset($wp_meta_boxes['dashboard']['normal']['high']['dashboard_browser_nag']); //Browse Happy
      remove_meta_box( 'dashboard_right_now', 'dashboard', 'core' ); //Right now
      unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_recent_comments']); //Recent comments
      unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_incoming_links']); //Incoming links
      remove_meta_box( 'dashboard_plugins', 'dashboard', 'core' ); //Plugins
      remove_meta_box( 'dashboard_quick_press', 'dashboard', 'side' ); //QuickPress
      remove_meta_box( 'dashboard_recent_drafts', 'dashboard', 'side' ); //Recent drafts
      remove_meta_box( 'dashboard_primary', 'dashboard', 'side' ); //Official WordPress blog
      remove_meta_box( 'dashboard_secondary', 'dashboard', 'side' ); //Other WordPress news
      //This also works for widgets inserted by plugins
      remove_meta_box( 'icl_dashboard_widget', 'dashboard', 'side' ); //WPML
      remove_meta_box( 'w3tc_pagespeed', 'dashboard', 'core' ); //W3 Total Cache
   }
   add_action('wp_dashboard_setup', 'remove_dashboard_widgets');

   You can improve this by hiding widgets from non-admins only:

   function remove_dashboard_widgets() {
      global $current_user;
      //This is hidden from everyone
      if ($current_user->user_level < 8) {
         //This is hidden from non-administrators
      }
   }
   add_action('wp_dashboard_setup', 'remove_dashboard_widgets');

   Or, if you're running Multisite, you can put this code in a must-use plugin (mu-plugins folder) and use it to hide widgets from specific sites:

   function remove_dashboard_widgets() {
      global $blog_id;
      //This is hidden from everyone
      if ($blog_id != 15) {
         //This is hidden from all sites but the one with ID 15
      }
      //Main blog has to be checked differently
      if (!is_main_blog()) {
      //This is hidden from all sites but the main one
      }
   }
   add_action('wp_dashboard_setup', 'remove_dashboard_widgets');

   As you see, you can play with this a lot.

   Hope it helps!

   Brilliant!
   Thank you for that.

   One thing :

   'User Levels were finally deprecated in version 3.0. '

   http://codex.wordpress.org/Roles_and_Capabilities#User_Levels

   How about:
   

   if ( current_user_can( 'administrator' ) ) {
       // whatever
   }

   That's not better unfortunately, current_user_can should take(and was intended to take) a capability, not a role name, despite the fact it works.

   You're right about user levels.

   According to the function reference, current_user_can may take a role as a parameter. But in order to achieve the same thing using capabilities, we could do something like this:

   if (current_user_can('manage_network')) {
      //whatever
   }
   
   if (current_user_can('activate_plugins')) {
      //whatever
   }

   In the examples, we assume manage_network is a superadmin capability and activate_plugins is a site admin capability. We could replace those two with any other which suit the specific needs of the case.
