我自己解决了这个问题，这很容易，我很惊讶没有其他人提供答案。话虽如此，解决方案是添加几行代码，检查您正在查看的配置文件的作者ID，并将其与当前登录用户的ID进行比较。

此代码位于members/single/profile的顶部。php

<?php
    // Global $bp variable holds all of our info
    global $bp;

    // The user ID of the currently logged in user
    $current_user_id = (int) trim($bp->loggedin_user->id);

    // The author that we are currently viewing
    $author_id  = (int) trim($bp->displayed_user->id);

    if ($current_user_id !== $author_id)
    {
    // redirect to home page url
        wp_redirect(home_url());
        exit();
    }
?>
