推荐答案

有一次我在生产服务器上遇到了同样的问题.直到前一天一切正常，但第二天，错误出现了.

Once I faced the same issue on my production server. until the day before everything was working good, but the next day, the error was showing up.

由于某些测试原因，我在长时间努力解决问题后，我已将应用程序池设置 -> 启用 32 位应用程序"更改为 True，而我的服务器是 64 位；我把它改回false，一切都正常了.

After long hours struggling with issue i remembered for some testing reasons, i had changed the "Application Pool Settings -> Enable 32-Bit Applications" to True, while my server is 64bit; i changed it back to false and everything got normal.

如果您的服务器是 32，则将此选项设为 True，否则设为 false.

If your server is 32 make this option True, otherwise make it false.
