 * On my WordPress installation, there is a problem after setting up the plugin 
   called “Warning Button”. The error is as follow:
 * `Fatal error: Call to undefined function get_blog_option() in /var/www/snat/data/
   www/syo.snat.co.uk/wp-content/plugins/warning-button/wb_frontend.inc.php on line
   24`
 * Just alerting the plugin author about this bug, I do not need help it.
