Exception Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. on IIS 7.0

Question

I am working on a already deployed web application on IIS version 6.0. I am using AJAX and there are some events on few pages where, async postback redirects to another page. It is working fine on server running on IIS 6.0.

Now, the issue is, We are shifting our web application to IIS 7.0 and I am getting this error on every AJAX call where it redirects to another page.

"Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error ...."

I have gone through this article.

Is there any other approach to solve this issue as it is working fine on IIS 6.0?
