I have got an error "server response error : Unknown server error" while uploading file using Ajax AsyncFileUpload, code behind functuion is triggered while uploading, but after code behind function executed, we are getting this error. Is any one can give me an idea why this error with Ajax?

Hi Buddy,

Problem fixed, I found a piece of code causing this problem, following is the code what I removed as I'm using pop up window for uploading images.

<script type="text/javascript">
function pageLoad() {
if (!opener) {
window.location = '../Default.aspx?signoff=1';
