 * Had to go into my Control Panel to delete the plugin. After activating the plugin,
   I got this message on the front page of my blog:
 * Fatal error: Call to undefined function is_admin_bar_showing() in /home/soulful1/
   public_html/mp3musiclounge.com/wp-content/plugins/wordpress-notification-bar/
   inc/class-plugin.php on line 120
 * I’ll have to find something more compatible.
