Hi,

After I upgraded my Rad controls to the latest version - Q2 2009, suddenly I started having issues. The solution is compiled without any errors. When I run the code I have the message: "A Runtime Error has occurred. Do you wish to Debug? Line:3 Error: Syntax Error". When I answer 'Yes', I see this line of code, that I believe is generated dynamically:
if (typeof(Sys) === 'undefined') throw new Error('ASP.NET Ajax client-side framework failed to load.');

If I disable all RadControls, I do not have this problem. I checked my web.config file and it seems to be in order. But I definately could've missed something.

Please help!

Here is my web.config file:

Hello,

Are you using RadScriptManager? If yes you can try setting the OutputCompression property to "Disabled" property to false.
This error means that the JavaScript file of ASP.NET Ajax fails to load for some reason. This is usually due to web resource related issues. I suggest you check this help topic which shows how to deal with the most common web resource issues. If this does hot help I suggest you check this blog post for instructions how to troubleshoot such issues.
