Hello,
Recently we've upgraded our framework version from 3.5 to 4.5.1. I'm receiving this error (the one in the title) when hitting a page with any Rad controls. We have actually recently upgraded our Telerik package, as we were using a 2009 version of your controls. So I've tried it using the older libraries, and the brand new ones, but I receive the same errors. I've had a look to see if there's any duplicate references to scripts, but cannot see any. Any ideas?
Thank you in advance for any help.
