    Hi All,

    I'm getting the following not found. Are there any tips on how to solve this? I'm using .NET 4.0 framework in Visual Web Developer 2010 Express. I have been looking at this for hours now and can't get it to work. 

    The call stems from this:

    <telerik:RadScriptManager ID="ScriptManager1" runat="server" />

    And gives a console error of the missing resource:


    Not Found (404)

    I've tried adding that location fix to my web config, removed references to runtimeversion2.0 etc. Scoured the web but nothing is helping, and leads anyone can give me would be super appreciated. I'm simply trying to get the HTML editor to function...

    Hi Guys,

    Our website has received numerous WebResource 404 errors after upgrading to .NET Framework 4.0 along with all Windows Updates for that framework.

    We did not have this issue with Telerik and .NET Framework 2.0.

    We have tried the suggestions given by the Telerik web site as to web.config changes to resolve 404 errors.  This did NOT work.  We also tried solutions given on the web such as turning off http compression.  This did not resolve the issue either.

    Here's a line from the W3SVC log showing a 404 error.

    We need an answer to this as soon as possible.

    Form the provided information it is not clear what exactly may be causing the described behavior. In such case I could only recommend you to refer to this help topic where you may find a possible solution. If it still does not help I would kindly suggest you to submit a support ticket from your Telerik account and send us a sample web page where the issue is isolated so we could inspect it and be more helpful.

    If you want to get updates on new releases, tips and tricks and sneak peeks at our product labs directly from the developers working on the RadControls for ASP.NET AJAX, subscribe to the blog feed now.

    It seems we were not able to replicate it at our side. You may try to isolate it and submit a support ticket about it so we could actually inspect it and be more helpful with a possible solution.
