This obiously means that you don't have ASP.NET 2.0 AJAX Extensions 1.0 installed on your machine. This assembly is used by the parent application (MonoX), and all settings from the parent MonoX web.config are propagated to the Blog web.config, however the correct DLL cannot be found in the BlogEngine bin folder. You may fix this issue by using any of the following:
1. install ASP.NET 2.0 AJAX Extensions 1.0
2. copy the System.Web.Extensions.dll and System.Web.Extensions.Design.dll from the MonoX /bin folder to the BlogEngine /bin folder
3. add the following tags in the
section of the BlogEngine Web.config
