SWFUpload在生产服务器上生成错误500

Question

我在我的网站上使用SWFUpload。当我在我的开发机器上测试SWFUploader时，它工作得很好。然而，当我转向生产然后它说“错误500”我检查了文件类型和文件大小，但似乎没有问题或冲突。我几乎使用标准设置..

     upload1 = new SWFUpload({
        // Backend Settings
        upload_url: '<%= Page.ResolveUrl("~/UserProfile/Photos.aspx") %>',


        // File Upload Settings
        file_size_limit: "1024*5", // 5MB
        file_types: "*.bmp; *.gif; *.jpeg; *.jpg; *.png;",
        file_types_description: "Image Files",
        file_upload_limit: "10",
        file_queue_limit: "0",

        // Event Handler Settings (all my handlers are in the Handler.js file)
        file_dialog_start_handler: fileDialogStart,
        file_queued_handler: fileQueued,
        file_queue_error_handler: fileQueueError,
        file_dialog_complete_handler: fileDialogComplete,
        upload_start_handler: uploadStart,
        upload_progress_handler: uploadProgress,
        upload_error_handler: uploadError,
        upload_success_handler: uploadSuccess,
        upload_complete_handler: uploadComplete,
        // Button Settings
        button_image_url: "../Images/XPButtonUploadText_61x22.png",
        button_placeholder_id: "spanButtonPlaceholder1",
        button_width: 61,
        button_height: 22,
        // Flash Settings
        flash_url: "../SWFUploader/swfupload.swf",


        custom_settings: {
            progressTarget: "fsUploadProgress1",
            cancelButtonId: "btnCancel1"
        },

        // Debug Settings
        debug: false
    });

这可能是造成此错误的原因..
