将App部署到实时服务器时出现500 Internal Server error - c#

我的ASP.Net Web应用程序在其中一个页面上上传了一个简单的Ajax文件，该文件在测试时可以在本地主机上正常运行，但是当我将其发布到网站时，出现500 Internal Server错误。以下是Google chrome控制台上的输出：

单击请求的URL，我在浏览器页面中收到此错误：

The resource cannot be found.

Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.  Please review the following URL and make sure that it is spelled correctly. 

Requested URL: /StoreManager/UploadFiles

香港专业教育学院还附上我的代码如下：

[HttpPost]
        public JsonResult UploadFiles()
        {
            var r = new List<UploadFilesResult>();

            foreach (string file in Request.Files)
            {
                HttpPostedFileBase hpf = Request.Files[file] as HttpPostedFileBase;
                if (hpf.ContentLength == 0)
                    continue;

                string savedFileName = Url.Content(Path.Combine(Server.MapPath("~/Images"), Path.GetFileName(hpf.FileName)));

                var path = GetNewPathForDupes(savedFileName);

                hpf.SaveAs(path);

                r.Add(new UploadFilesResult()
                {
                    Name = "/Images/" + Path.GetFileName(path),
                    Length = hpf.ContentLength,
                    Type = hpf.ContentType
                });
            }
            return Json(r);
        }

        private string GetNewPathForDupes(string path)
        {
            string directory = Path.GetDirectoryName(path);
            string filename = Path.GetFileNameWithoutExtension(path);
            string extension = Path.GetExtension(path);
            int counter = 1;

            string newFullPath;

            do
            {
                string newFilename = "{0}({1}){2}".FormatWith(filename, counter, extension);
                newFullPath = Path.Combine(directory, newFilename);
                counter++;
            } while (System.IO.File.Exists(newFullPath));

            return newFullPath;
        } 

我的HTML和javascript代码：

$(document).ready(function () {
            $('#fileupload').fileupload({
                dataType: 'json',
                url: "/StoreManager/UploadFiles",
                autoUpload: true,
                done: function (e, data) {
                    var json = data.result[0];

                    $("#picurl").val(json['Name']);

                    $('.file_name').html(json['Name']);
                    $('.file_type').html(json['Type']);
                    $('.file_size').html(json['Length']);
                }
            }).on('fileuploadprogressall', function (e, data) {
                var progress = parseInt(data.loaded / data.total * 100, 10);
                $('.progress .progress-bar').css('width', progress + '%');
            });
        });

参考方案

浏览服务器设置后，我看到写权限被禁用。启用AJAX后，上传将按预期工作。
