Hi All,
I have started to get this intermittent error when I try to open my web site. The starting page uses the Accordion AJAXToolKit Control and a couple of update panels. I noticed that the PageRequestManagerParserErrorException error does not occur every time. Has anyone encountered this error and figured out the solution to this problem?
Thanks in advance

Great thanks. That helped me out. For others benefit I will just post a short blurb of the problem and the resolution. To start with the URL above is very informative.
The problem was that I am using a login control where the user enters the username and password and logs into my website. In my Login Control I had set the DestinationPageUrl to the page I wanted to display after the user was successfully logged in. The problem was occuring when that page was being displayed as it has a few update panels and I guess the client browser was receiving html that it did not know how to render. Thus the ParseRequestManagerParserErrorException.
Resolution: I changed my code to handle the "LoggedIn" event of the Login Control. I do an explicit Response.Redirect to display the page I want to display. This fixed the problem.
I am wondering if the Login Contol does a Server.Transfer instead of response.redirect. I know that the URL above mentions that a Server.Transfer can cause the problem to occur. Anywho I am happy :)
