我根据网站安装了wordpresshttps://ipipe.ru/info/ustanovka-wordpress-na-openserver 然后想用下划线。我进入worldelectronics并按下generate按钮（结果，一个请求似乎覆盖了wordpress文件）。

致命错误：未捕获错误：调用C:\\OSPanel\\domains\\worldelectronics中未定义的函数get\\u header（）。ru \\索引。php:15堆栈跟踪：#0{main}在C:\\OSPanel\\domains\\worldelectronics中抛出。ru \\索引。php在线15

以下是索引。php文件

    <?php
    /**
     * The main template file
     *
     * This is the most generic template file in a WordPress theme
     * and one of the two required files for a theme (the other being style.css).
     * It is used to display a page when nothing more specific matches a query.
     * E.g., it puts together the home page when no home.php file exists.
     *

    get_header();
    ?>

        <main id="primary" class="site-main">

            <?php
            if ( have_posts() ) :

                     */
                    get_template_part( \'template-parts/content\', get_post_type() );

                endwhile;

                the_posts_navigation();

            else :

                get_template_part( \'template-parts/content\', \'none\' );

            endif;
            ?>

        </main><!-- #main -->

    <?php
    get_sidebar();
    get_footer();

如何从下划线中获取worldelectronics主题的主页。要显示的me？
