Php 引导切换导航和AJAX在Localhost上工作，但不在webhosting上工作，也不在我的计算机上工作

请帮帮我

我的网站上的一些功能PHP在服务器上不能很好地工作，当我将我的网站文件复制到新目录时，它也不能工作。当我试图上传到数据库时，它也不能工作

请帮帮我。

你基本上是说它在任何地方都不工作..？它只是在一个文件夹上工作，当我复制到另一个目录时，它在新目录上不工作，但在旧目录上仍然工作。首先，我想的是文件夹结构是否完好无损。？src和href属性可能会出错。请访问并使用该文件夹，当我要在工作文件夹的浏览器中以匿名模式访问时，它无法工作，并且不能在一个页面中切换，但不能在所有页面中切换。
