Commented Unassigned: Resolved: AjaxFileUploader April 2013 Upload Error [27416]

I resolved this problem. I did not have the correct entries in web.config

I just update to the latest version of the Ajax Control Toolkit. I am using the AjaxFileUploader and I am now getting the following ASP exception. I was not getting this with the prior release. Could this be a permissions issue? I'm running IIS Web Server on Windows 2003 R2 Server. THe application is using ASP Version 4.0.30319

Comments: Something that's also weird is that in the sample site that comes with the toolkit, the ajaxfileupload works fine in IE9. The "Drop Files Here" doesn't show, but at least the upload works. I have tried matching up everthing in the sample site with my site, but I just cannot get it to upload the file...
