For the DNN RadUpload, on this page of the support site http://www.telerik.com/help/aspnet-ajax/upload_troubleshootingerrormessages.html
it says to for IIS 7 in integrated mode (which we are) to do add :
<system.webServer>
<modules>
. . .
<add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule, Telerik.Web.UI"
preCondition="managedHandler"/>
</modules>
<handlers>
. . .
<add name="Telerik.RadUploadProgressHandler.ashx_*" path="Telerik.RadUploadProgressHandler.ashx" verb="*" type="Telerik.Web.UI.Upload.RadUploadProgressHandler, Telerik.Web.UI" preCondition="integratedMode,runtimeVersionv2.0"/>
</handlers>
</system.webServer>
When added the RadUploadModule line in the Modules section there, the application fails disasterously and gives me this run time:
Collection is read-only.
Server Error in '/' Application.
Collection is read-only.
Description:
