I would like to know that too!

I’m having the same problem!
I’m not a developer, but the following change to wp-post-navigation.php appears to have worked for me.
Please someone let me know if I’ve done something silly!
Towards the end of the file I commented out one line (with //) as shown:
if(isset($WPPostNavigation)){
register_activation_hook(__FILE__, array(&$WPPostNavigation, 'WP_Post_Navigation_install'));
add_filter('wp_head', array(&$WPPostNavigation, 'wp_post_navigation_HeadAction'));
// add_filter('the_content', array(&$WPPostNavigation, 'WP_Pre_Next_Navigation_Bottom'));
add_action('admin_menu', array(&$WPPostNavigation, 'wp_admin_menu'));
add_action( 'wp_enqueue_scripts', array(&$WPPostNavigation, 'wp_post_navigation_stylesheet'));
