我有一个特定的模板，只显示类别（350）中的帖子。当我为帖子分页时，帖子保持不变。下面是组成此模板的一些代码。有没有办法纠正这个问题？

<?php if (is_front_page()) { ?>
    <?php get_template_part(\'home\'); ?>
<?php } else { ?>   
    <?php 
    $et_ptemplate_settings = array();
    $et_ptemplate_settings = maybe_unserialize( get_post_meta($post->ID,\'et_ptemplate_settings\',true) );

    $fullwidth = isset( $et_ptemplate_settings[\'et_fullwidthpage\'] ) ? (bool) $et_ptemplate_settings[\'et_fullwidthpage\'] : false;

    $et_ptemplate_blogstyle = isset( $et_ptemplate_settings[\'et_ptemplate_blogstyle\'] ) ? (bool) $et_ptemplate_settings[\'et_ptemplate_blogstyle\'] : false;

    $et_ptemplate_showthumb = isset( $et_ptemplate_settings[\'et_ptemplate_showthumb\'] ) ? (bool) $et_ptemplate_settings[\'et_ptemplate_showthumb\'] : false;

    $blog_cats = isset( $et_ptemplate_settings[\'et_ptemplate_blogcats\'] ) ? (array) $et_ptemplate_settings[\'et_ptemplate_blogcats\'] : array();
    $et_ptemplate_blog_perpage = isset( $et_ptemplate_settings[\'et_ptemplate_blog_perpage\'] ) ? (int) $et_ptemplate_settings[\'et_ptemplate_blog_perpage\'] : 10;
    ?>

        <div id="content" class="clearfix<?php if($fullwidth) echo(\' pagefull_width\');?>">
            <div id="content-area">

                    <h1 class="title"><?php the_title(); ?></h1>
