ASPX + Portal Page - The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases

Using version 7.0.12, .NET 4.0

I have a site using aspx, and I am attempting to setup a page template to use ASPX + Portal page. I have added the portal manager and script manager to my master page:

<cms:CMSPortalManager runat="server" ID="manPortal" EnableViewState="False" />
<ajaxToolkit:ToolkitScriptManager runat="server" ID="manScript" EnableViewState="False" ScriptMode="Debug" />

However, I now get an error on any Page tab in the CMSDesk, as well as on the Design tab on any pages that use the new template:

[HttpException (0x80004005): The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.]

   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +2098

I've seen this thread, which points to another thread that supposedly solves the error, but neither of the solutions solves my issue. Does anybody have a solution that works?

Thanks.

RE:ASPX + Portal Page - The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases

Hello,

Please take a look at our Developers Guide: Creating ASPX master pages
where you can find the following sentence near CMSPortalManager... Always place this control after the ToolkitScriptManager control. + you can find there example codes. The order is important.

Best regards,
Martin Danko
