我是WordPress的新手。我的问题是我创建了一个名为Atividades 当我创建帖子时，它不会出现在网站上。

// fuctions.php
add_action( \'init\', \'create_post_type\' ); function create_post_type()
{ register_post_type( \'acme_atividade\',         array(          \'labels\' => array(
                \'name\' => __( \'Atividades\' ),
                \'singular_name\' => __( \'Atividade\' )            ),      \'public\' => true,       \'has_archive\' => true,      )   ); }

// index.php
<div id="atividades">
                    <div id="col1">
                        <div style="background: url(\'<?php echo $thumbnail; ?>\') no-repeat;" id="q-1">

                <?php
                $thumbnail = \'\';
                if (function_exists(\'has_post_thumbnail\')) {
                if ( has_post_thumbnail() ) {
                $thumbnail = get_the_post_thumbnail($post->ID,\'thumbnail\');
                }
                }
                ?>

                <?php 
                query_posts(array( 
                \'post_type\' => \'Atividades\',
                \'posts_per_page\' => 1 
                ) );  
                ?>

                <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

                <?php if ( has_post_thumbnail() ) { the_post_thumbnail(); } ?>

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

                <?php the_content(); ?>

                <?php endwhile; else: ?>

                <h1 class="title">Ups...</h1>

                <p>... pedimos desculpa mas nenhum <em>post</em> foi encontrado!</p>

                <?php endif; ?>

                <p align="center"><?php posts_nav_link(); ?></p>

            </div>
                        </div>
                        </div>
