I was able to fix Edit Flow's icon with a few lines of CSS: #adminmenu #toplevel_page_ef-settings div.wp-menu-image:before { content: "\f327"; } #adminmenu #toplevel_page_ef-settings div.wp-menu-image img { display: none; } You can include the CSS code in a plugin, theme's functions.php or code snippet by wrapping it with this PHP code: function replace_admin_menu_icons_css() { ?> /* CSS code goes here */ <?php } add_action( 'admin_head', 'replace_admin_menu_icons_css' ); See this post for more information: http://bungeshea.com/change-wordpress-admin-menu-icons/
