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: Thanks Kevin, I have checked my layout, but moving my aspx page to the root folder did not solve it either. If I create a new empty web site in VS2010 and put the control on the default.aspx it still doesn't work in IE, but works in Chrome.
