* ASP.NET Ajax client-side framework failed to load.

* 'Sys' não está definido.

PS: im using FW 4.0.

Can anyone help me? Thks

Hi cayo,

Can you please verify that you granted permissions for all users to operate with the Telerik.Web.UI.WebResource.axd handler? How to do that you can see from the relevant paragraph of this article in the product documentation.

You may also try replacing temporary RadScriptManager with asp ScriptManager or set its EnableScriptsCombine property to false to compare the results. Additionally, make sure you use the latest version 2010.1.519 of the suite.

Best regards,
