我有一只奇怪的虫子。我从一个特定的帖子中得到了相同的评论，每个帖子都是“Hello world”！但是，当我删除了我试图创建的一个最近发布的小部件的一些代码时，这个bug消失了。。。以下是最近发布的小部件的代码：

class Hype_Recent_Posts extends WP_Widget {

    public function __construct() {
        parent::__construct(
            \'hype_rp\', // Base ID
            __(\'Paradox Recent Posts\', \'hype\'), // Name
            array( \'description\' => __( \'Display your recent posts, with a Thumbnail.\', \'hype\' ), ) // Args
        );
    }

    public function widget( $args, $instance ) {
        $title = apply_filters( \'widget_title\', $instance[\'title\'] );
        $no_of_posts = apply_filters( \'no_of_posts\', $instance[\'no_of_posts\'] );

        echo $args[\'before_widget\'];

        if ( ! empty( $title ) )
            echo $args[\'before_title\'] . $title . $args[\'after_title\'];

        // WP_Query arguments
        $qa = array (
            \'post_type\'              => \'post\',
            \'posts_per_page\'         => 5,
            \'offset\'                 => 0,
            \'ignore_sticky_posts\'    => 1

        );

        // The Query
        $recent_articles_wtb = new WP_Query( $qa );
        if($recent_articles_wtb->have_posts()) : ?>
        <ul class="rp">

            while($recent_articles_wtb->have_posts()) :
