好的，所以我成功创建了我的第一个 codeigniter 项目并使用 Tank Auth 进行 CMS 身份验证。在我的 MAMP 安装上一切正常，并且一旦上传到我的主机仍然可以工作。
然后我在我的 mamp 安装中将文件复制到一个新项目并更改了一些配置设置（新数据库、基本 url 等）一切正常，一旦这个新项目上传到服务器，我就无法登录到 CMS。
表单看起来好像已提交，但登录页面只是再次加载。无效的用户名/密码没有错误。
如果您尝试使用注册表格，同样的事情会发生，提交并且没有错误，它似乎只是刷新了页面并且没有创建用户。
关于尝试什么的任何想法，因为这真的很令人沮丧！几乎就好像 tank auth 库无法正常工作，因为没有错误。

更新： -
我已经上传到另一个域名但同样的服务器，它工作正常。这显然不是编码问题，但如果有人能阐明一些观点或提出建议，将不胜感激
