[Ahmet HOSO]

Hi Guys,

I publish my web app to several server. But one of my installation returns ajax exceptions. I check the system date and it's correct.

You can find the fiddler detail and ie error message below.

Hello Ahmet,

Can it be that you have not granted permissions to all users for the Telerik.Web.UI.WebResource.axd handler as depicted in the corresponding paragraph of this help topic? This can cause the error to appear. Enable the access for all users via the web.config to see whether this helps.

Best regards,
Sebastian
