好的，

所以我不知道为什么现在按预期运行.我的管理员让我进行了一些安全更新和硬件重启，之后它只适用于标准的 php 会话函数和我的 SecureSessionHandler 函数.

so I do not know why this is now running as intended. My admin had me do some security updates and a hardware reboot and afterwards it just works with standard php session functions and with my SecureSessionHandler functions.

我想某些东西已经崩溃或阻止了对所需文件的访问.

I suppose something had crashed or blocked access to a file that was needed.

不过还是谢谢你的帮助.

But none the less, thank you for your help.
