Hello
I'm migrating to v9 (from v7). I have some issue with modules that contains RadCaptcha. In my server environment I got this error:

"Cannot unregister UpdatePanel with ID '' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.
Parameter name: updatePanel"

The strangeness is that if I create a new instance of DNN in my laptop, I got no issues at all. I check difference in web.config files but I see no significative differeces.
Any Ideas?
Thanks

Fabio,

the Telerik controls have been moved to another namespace (DotNetNuke.Web.Deprecated afair). If you have written these modules, you should change your code (fast solution is to reference this namespace, good solution is to replace the RAD UI controls).

If not you should look for a newer version of the module.

Happy DNNing!
Michael
