由于我的上一个（第一个）插件在一个文件中有6个管理页面，因此有点难以管理，我决定将它们拆分为这一个，但这样做只会带来问题。

在我的插件函数文件（LoadPressFunctions.php）中，我有以下内容：

add_action( \'admin_menu\', \'my_plugin_menu\' );

function my_plugin_menu() {
    add_menu_page( \'LoadPress\', \'LoadPress\', \'manage_options\', \'LoadPressPlugin\', \'LoadPress_Plugin\', \'dashicons-download\', 99  );
}

function LoadPress_Plugin() {
    if ( !current_user_can( \'manage_options\' ) )  {
        wp_die( __( \'You do not have sufficient permissions to access this page.\' ) );
    }
    include \'LoadPressOptions-Home.php\';
}

在我的加载中，按Options Home。php文件我有：

<?php
echo \'<style>
    h1 {
        letter-spacing: 8px;
    }
    .sectionHeader {
        background-color: #E5E5E5;
        padding: 1px 10px 1px 10px;
        margin: 10px 0px 0px 0px;
        border-left: 4px solid #2A333E;
    }
    .sectionNotification {
        background-color: #E5E5E5;
        padding: 1px 10px 1px 10px;
        margin: 5px 0px 0px 0px;

    }
    ul#adminmenu a.wp-has-current-submenu:after, ul#adminmenu>li.current>a.current:after {

    <h3>Thank You for choosing LoadPress</h3>

    <h3>What is LoadPress?</h3>
    <p>LoadPress is a professional plugin that allows site community members to post downloadable files, such as modifications, save files and other community applicable files.</p>
    <p>This plugin was developed for use primarily with modding communities for video games, and other video game related products, and uses a simplistic yet robust setup with several different fallbacks in case of mistakes.</p>
    <p>At the time of writing this, LoadPress is primarily used for in-house projects developed by Kyle Briggs & Don Briggs Ltd.</p>
    </div>

    <div class="sectionHeader">
    <h3>Why LoadPress?</h3>
    <p>LoadPress is an excellent choice for targeted community functionality as it offers several things other plugins do not:</p>
    <ol>
        <li>It allows users to upload files in any format (settable by editing the plugin).</li>
        <li>It allows total administrative control over all files, but only gives regular users access to their own.</li>
        <li>It simplifies the Media section to only display a regular user\'s own media (admins can see all).</li>
        <li>It is the ONLY plugin currently available for Wordpress that offers this functionality tailored specifically to file-sharing, and works seamlessly with any SEO package.</li>
        <li>At the core, it runs on Wordpress\' own API so the custom post type can be edited to your needs easily.</li>
    </ol>
    </div>

    </div>
    <?php

但现在我得到了一个空白页，因为我已经将此内容从主文件移动到了自己的文件，没有从中加载内容。

如果我将文件内容替换为：

<?php
echo \'<h1>Hi</h1>\';

一切正常，但我看不到Home有任何语法错误。php内容，因为它是直接复制和粘贴出来的功能（并添加了任何想法？

define(\'WP_DEBUG\', false);

define(\'WP_DEBUG\', true);
