这是我的一个客户案例。
首先我们来看一下官方文档的说明：
As of WP 4.3, a plain text password is no longer passed to the function. If you have a plugged version of this function and are assuming that the second function argument is $plaintext_pass, the password displayed in your email to the user will be "admin" or "both".
大概的意思是：在WP 4.3版本中，纯文本密码将不会传递给函数，在您的电子邮件中密码将被显示成“admin”或“both”。
其实在WP 4.3用户注册机制已经发生改变，用户现在需要点击邮箱中发来的链接，自己设置密码。
把插件修改成类似以下代码吧，官方文档的不好使，会提示验证链接不对。
- <?php
