【问题描述】：
所以。我在这个 Wordpress 网站上工作。相信我这太烦人了。所以我有大量的代码，它是 PHP 和 HTML 的组合。在提交表单之前，一切看起来都很好。当页面刷新时，它会加载到同一页面（具有相同的确切 URL）但出现 404 错误。

如果您有任何想法可能导致此问题，请提供帮助！
【问题讨论】：
-
现在您已经公开发布了您的数据库用户名/密码，您应该更改它们。
-
你有一些诡计。开始在 apache、php 和 wordpress 错误日志中寻找答案。
-
表单如何知道在哪里发布？以防万一，确保您有一个指定 PHP_SELF 的操作，因为您希望该页面在那里发布。
-
@cosmoonot 默认情况下，表单会发布给自己。
-
你说的很对。我已经习惯于指定它了。
