title: Error: Sys.WebForms.PageRequestManagerparserErrorException: The message received from the server could not be parsed
body: <p>Hi I am getting below Error
  "Error: Sys.WebForms.PageRequestManagerparserErrorException: The message received from the server could not be parsed"</p>
  
  <p>When I click button on my User Control. User control does not have any Update Panel but the page in which user control will be loaded has an update panel.</p>
  
  <p>I don't see this issue on my local machine, I get this only when I DEPLOY to server..</p>
  
  <p>How can I fix this and also how Can I Test this as it does not show error in local machine ??</p>
