当我点击分页链接上的“2”时，我得到一个404错误。url正确更改为http://mysite.com/?paged=2

<?php
/**
 * The loop that displays the posts.

<ul class="post-items">

    $args = array(
        \'post_type\' => array(\'post\', \'wr_raffle\'),

        \'paged\' => (get_query_var(\'page\')) ? get_query_var(\'page\') : 1,
    );

    $loop = new WP_Query( $args );
    while ( $loop->have_posts() ) : $loop->the_post(); ?>

我已经刷新了永久链接。不起作用。
