I am trying to integrate telerik controls into a web application that was recently upgraded from .net 1.1 to 4.5. Needless to say the pages and configs contain all sorts of quirky legacy stuff . I have set up a test page in this webapplication. On this page I am completely unable to get the RadNavigation control to run. I have it set up as in the Demo. No code behind. I always get a javascript error from the browser on the initial display of the page.
Unhandled exception at line 40, column 40 in http://aspnet-scripts.telerikstatic.com/ajaxz/2016.1.113/Navigation/RadNavigationScripts.js
0x800a138f - JavaScript runtime error: Unable to get property 'toLowerCase' of undefined or null reference
If I check fiddler I don't see a tolowercase call on this line.
Any help on this one. I'm guessing it's some sort of config issue since I'm not actually trying to do anything other than get a very very basic sample to run.
Thanks!

I replied in the other thread with the same subject you started in the Ticketing system. Please, let us know whether the suggested changes to the web.config resolve the issue.
