Codeigniter do_upload功能在Godaddy服务器上不起作用

Question

我在我的系统中使用Codeigniter（版本3）和图像上传功能。但是在GoDaddy服务器上运行时它无法正常工作。它在localhost和其他一些实时服务器上工作正常。只有在godadddy上它才能正常工作，之前它正在显示文件权限，所以我将完全控制权改为用户，现在它显示500错误。检查错误图片我尝试了很多方法，但无法获得解决方案。请帮帮我。

Codeigniter系统安装在主系统的文件夹中 www.mywebsite.com/admin

www.mywebsite.com/admin/.htaccess

RewriteCond $1 !^(index\.php|resources|robots\.txt)
