The problem still persists.

I am using a Visual Studio 2008 Standard, Windows 7, Framework 3.5, ASP.NET Web Application.

How can I fix this issue?

Thank you.

Comments: I had similar issues. I created my problems because, for security reasons, I limited the length of the url and query strings. This was my original web.config configuration line: ``` <configuration> <system.web> <httpRuntime enableVersionHeader="false" maxRequestLength="4096" maxQueryStringLength="__120__" maxUrlLength="__160__" /> </system.web> </configuration> ``` When I changed the bold face values to these amounts, I could get the ToolkitScriptManager to load: (I make no guarantee that these are the right numbers for your application.) ``` <configuration> <system.web> <httpRuntime enableVersionHeader="false" maxRequestLength="4096" maxQueryStringLength="__224__" maxUrlLength="__384__" /> </system.web> </configuration> ```
