We have recently migrated from SharePoint 2010 to 2013. In our site we have the registration control with ajax update panel which is working fine in all the pages other than home. After analysis, I found that this issue is happening only if the popular items web part exists (which comes under "search-driven content" category). The issue occurs whenever I attempt to do a partial postback. I'm not getting anything changed and instead I'm seeing an error in the browser console. Please find the error details below:

I have my update panel code as below:

<asp:UpdatePanel class="something" ID="something" runat="server" UpdateMode="Conditional" 
                        ChildrenAsTriggers="true">
                        <Triggers>
                            <asp:AsyncPostBackTrigger ControlID="something" />
                        </Triggers>
                        <ContentTemplate>
                            <img id="something" alt="Captcha Image" title="Captcha Image"
                                runat="server" />
                        </ContentTemplate>
                    </asp:UpdatePanel>

In my code behind, what am i trying is, to refresh the captcha image which involves assigning the .aspx url to the image. The assigned .aspx image have the logic for writing back the new image.

I have tried changing the IIS settings with respect to idle time and framework type(integrated/classic)..

    Well, then you have to get more reputation points by helping others, and gain reps before you can use them.

Take a look here: http://msdn.microsoft.com/en-us/library/ff650218.aspx

In Visual Studio, add a reference to Microsoft.Practices.SPG.AJAXSupport.dll. Add a SafeScriptManager control to your page and set the EnableUpdatePanelSupport flag to true. This changes the postback script that is needed for the UpdatePanel control to work in a SharePoint environment.

Example code:

<%@ Register 
   Assembly="Microsoft.Practices.SPG.AJAXSupport, Version=1.0.0.0, Culture=neutral, PublicKeyToken=8768CCAE1C3C9EB2"
   TagPrefix="spg" 
   Namespace="Microsoft.Practices.SPG.AJAXSupport.Controls" %>

<spg:SafeScriptManager ID="SafeScriptManager" 
                                                   runat="server" 
          EnableUpdatePanelSupport = “True”
                                                   />

<asp:UpdatePanel runat="Server" id="MyUpdatePanel">
 ...
</asp:UpdatePanel>

I solved the issue by changing the loading behaviour option in the popular content web part. Changing the default "Sync" to "Asyn" under the settings did the job. Reference URL
