php - 错误 PHP 通知：未定义变量：第 57 行 /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/Lost-password/lost-passwords.php 中的 _SESSION

Question

我对 php 非常陌生，并且是那种如何遵循教程并尽力做到最好的人，但是我在 WooCommerce 上的自定义重置密码表单上遇到了一些麻烦......

我已经按照@Polar在另一个页面答案上的 WooCommerce 丢失密码表单上给出的所有步骤进行操作。但我无法获得重置密码表单，当我激活调试模式时，出现以下错误：

“PHP 通知：未定义变量：…/wp-content/plugins/Lost-password/lost-passwords.php 第 54 行中的 _SESSION”

这是在第 54 行写的：

unset( $_SESSION[ "csx-show-reset-form" ] );

我可以输入用户电子邮件并实际收到重置密码的电子邮件，但是当我点击链接时，它再次显示“插入您的电子邮件”页面。

这是我正在使用的代码：

<?php

        wp_redirect( home_url() . '/password' );
        exit;
    }

我会感谢你能给我的任何帮助。
