WordPress- disable plugin update

Add this code in your plugin root file. It will prevent plugin updates notifications.

add_filter('site_transient_update_plugins', 'remove_update_notification');
function remove_update_notification($value) {
     unset($value->response[ plugin_basename(__FILE__) ]);
     return $value;
}

 
Other solution can be used in theme functions.php file. Here you need to change plugin main file url to match your case:

 function my_filter_plugin_updates( $value ) {
    unset( $value->response['facebook-comments-plugin/facebook-comments.php'] );
    return $value;
 }
 add_filter( 'site_transient_update_plugins', 'my_filter_plugin_updates' );
