Do you have 2 ScriptManagers on the page?

Hi Frinavale,

I have only 1 script manager but still i am getting error.I am using scriptmanager in another aspx page there i am not getting any error.

Earlier it was working fine from the past 3 days i am getting this error.

Most of the time when I encounter that error I am trying to run something in the ASP.NET Ajax Library when the page has been unloaded (or is unloading) and the Library is no longer available.
