Could you please check the server's GAC and make sure that the following assemblies are present:
- System.Web.Extensions
- Telerik.Web.UI
- Telerik.Charting
- RadEditorSharepoint
I hope this helps.

I think the problem is that I have .NET 3.5 installed on my SharePoint server, which means that the System.Web.Extensions assembly is version 3.5.0.0 instead of 1.0.61025.0.
This is weird though because the rad ajax controls worked fine when I installed them into the GAC. Any idea on how to make the radEditor work on a SharePoint server with .NET 3.5 installed?
The following assemblies are all in the GAC on my machine:
- System.Web.Extensions (3.5.0.0, NOT 1.0.61025.0)
- Telerik.Web.UI
- Telerik.Charting
- RadEditorSharepoint

The RadEditor for MOSS is built using the Microsoft ASP.NET Ajax Extensions 1.0 (version 1.0.61025.0). Since you are using different versions (3.5.0.0 for System.Web.Extensions and 2008.x.xxx.35 for Telerik.Web.UI) you will need to add <bindingRedirect> elements for those two assemblies in the web.config file.
<dependentAssembly>
<assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="1.0.61025.0" newVersion="3.5.0.0" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="Telerik.Web.UI" publicKeyToken="121fae78165ba3d4" culture="neutral" />
<bindingRedirect oldVersion="2008.x.xxx.20" newVersion="2008.x.xxx.35" />
</dependentAssembly>
This should allow SharePoint to get the proper references and display the editor. I hope this helps.

Thanks! I had just tried that previously to your response and got it to work.
Thanks again,

Hi,
I'm running into a similar issue. I have the following bindingRedirect in my web.config, which should cover the 1.0.61025.0 version mentioned in the error --
<dependentAssembly>
<assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0" />
</dependentAssembly>
I do see System.Web.Extensions registered in the GAC. The editor does appear to be working on our MOSS based site, but that error message continues to periodically appear in the server application event log.

Make sure that you extended your MOSS site with ASP.NET AJAX according to the following help article Extending your MOSS site with Microsoft ASP.NET AJAX 3.5.
If after reviewing the article the problem persists, provide me with your web.config file. I will check if there is something wrong regarding the RadEditor in it.
If you upgraded your version of the control you can review the following help article as well Upgrading to a newer version of RadEditor for MOSS.

If you want this error to stop appearing in the logs, you have two options.
1. Install ASP.NET AJAX 1.0 regardless of the fact that the old version of System.Web.Extensions will not be used.
2. Use the 3.5 version of Telerik.Web.UI.dll. In order to do this add the xxxx.x.xxx.35 version of the dll in the GAC and add the following binding redirect in the web.config of your MOSS site:
<
dependentAssembly
>
<
assemblyIdentity
name
=
"Telerik.Web.UI"
publicKeyToken
=
"121fae78165ba3d4"
/>
<
bindingRedirect
oldVersion
=
"1.0.0.0-xxxx.x.xxx.20"
newVersion
=
"xxxx.x.xxxx.35"
/>
