I have looked around in the web and it seems, that you are using a PHP Version which is to old … What version of PHP are you using?
Try to replace the code above in the msnb-notice-board.php with the following. If the problem is fixed then, I will change it for the next update.
/**
* Register Notice Board widget on Widgets Initialization
*/
function register_Notice_Board_Widget() {
register_widget( 'Notice_Board_Widget' );
}
add_action( 'widgets_init', 'register_Notice_Board_Widget' );
