Postback Error?
<p>I wonder why if anyone has idea of this error?
My ASP.Net page was working fine when publish on my Win7 IIS7 and on another Server 2008 IIS7, but today when I do the same one for another Server 2008, all the ajax postback gives this error:</p>

<pre><code>#Exception Message:

   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean&amp; completedSynchronously)
</code></pre>

<p>I wonder what will be the possible reason for the error?</p>

<p>Thanks in advance...</p>
