It seems you have early version fo DNN 5 where ToJson is not implemented yet. 

To Fix your site you have to

  • Go the DNN files root and open App_Code\XsltDb\XsltDbController.cs
  • Find definiton of XsltDbExtensions class
  • Add the following extension method declaration

        public static string ToJson(this object source)
            return new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(source);

After that your site should be OK.

ASAP I'll issue new release that will not contain ToJson and test it on DNN 5.0 to ensure it is supported.

No, that's not enough.

You have to add one more method at the same point

        public static T FromJson<T>(this string json)
            return new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<T>(json);

After that Your site will run.

I have prepared a new release that I tested on DotNetNuke 05.01.00

You can download it from here

I don't create a new release here now as I don't have enough time to create a description.

If you still can't get your site up - just delete all files in App_Code\XsltDb folder (the XsltDb folder itself should exist on disk!!!!). After that your site will run and you will be able to setup fresh XsltDb.

If any troubles - post a message here.
