    Hi,
       This is an exception i get in my application, This doesn't happen often, but happens some times

    Message: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

    Details: Error parsing near '

    <!DOCTYPE html PUB'.

    Can any one please help me on this?

    Thanks shinu , I have already read the link from other posts.But couldn't find the root cause in my code.
    And another thing is it doesn't happen every time am on the page, happens only very rarely.
