I am getting the following error as javascript alert window while uploading files with RadUploader :

RadUpload Ajax callback error. Source url returned invalid content :

< !DOCTYPE html PUBLIC "-//W  3C //DTD XHTML 1.0 Transitional  //EN " "http :// /TR /xhtml 1 /DTD  /xhtml 1 -transitional .dtd ">

< html xmlns  =" http ://www   .w 3 .org /1999  /xhtml " >
< head  >
<title> Untitled Page   < /title>
<script type  =" text /javascript " src="" originalAttribute="src" originalPath="" originalAttribute="src" originalPath="" >
    alert('A critical error occured in the system.Please contact support.);
< /head  >
< body  >
< /body  >
< /html >

                 Telerik .RadUploadProgressHandler.ashx  ?RadUrid   = 73 a59 d 1d -d4 da -4c 6a -a1 a1 -1eaf 178  eaa 59
Did you register the RadUploadProgressHandler in web.config ?

                Please  ,see the help for more details : RadUpload for ASP.NET Ajax    - Configuration    -RadUploadProgressHandler.

I have registered Telerik.RadUploadProgressHandler.ashx  in the web.config as instructed in the manual. And this error has almost random but frequent occurrance; I couldn't find out any specific reason for this error pop-up.

Any help regarding this matter would be highly appreciated.

Hi Sadeka,

This is indeed strange. Can you send us a sample running code so we can reproduce the error?
