我已经为我的Wordpress站点构建了一个自定义注册表单，尽管它具有完整的功能，但对于username\\u exists和email\\u exists，我都会收到验证错误。

事情就是这样：

如果我填写的注册表有任何错误，它不会注册，并且会产生正确的错误。

如果我填写的注册表没有错误（以及唯一的用户名和电子邮件），它会正确注册并插入用户数据。但它仍然会生成username\\u exists和email\\u exists错误。

几周来，我一直在努力解决这个问题，但一直没有找到解决方案。如果需要，我很乐意提供代码。

非常感谢。

（主插件代码-如果格式不对，很抱歉。仍在习惯论坛）
