Hello Mano,

Here are the most common reasons for getting PageRequestManagerParserErrorException:

-    Calls to Response.Write()
-    Calls to Response.Redirect()
-    Response filters
-    HttpModules
-    Server trace is enabled
-    Calls to Server.Transfer()

It is hard to say what is causing this problem without seeing some code. Can you please open a support ticket and provide a sample app that recreates this problem or post some sample of your code here in this thread. We will check it and do our best to help.
