    Problem with Member.AddMemberToCache

    I've succesfuly implemented Facebook login on Umbraco in my local development environment running Umbraco 6.0.5.

    On the production server however, i only get errors when trying to login with Facebook.

    I have located the problem to the method Member.AddMemberToCache. If i comment out those two rows i don't get any errors (but the member isn't logged in either).

    MESSAGE: Exception has been thrown by the target of an invocation. STACKTRACE: at System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments, Signature sig, Boolean constructor)
     at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object[] parameters, Object[] arguments)

     at Umbraco.Web.BaseRest.RestExtensionMethodInfo.Invoke(String[] parameters) INNEREXCEPTION: System.NullReferenceException: Object reference not set to an instance of an object.
     at MyProject.FacebookLogin.createNewUser(Object facebookUser)
     at MyProject.FacebookLogin.LogUserIn()

    Here is a piece of my code that is throwing errors.

    private static String createNewUser(dynamic facebookUser)
                MemberType siteUser = new MemberType(1088); // Facebook user type
                Member newMember = Member.MakeNew(,,, siteUser, new umbraco.BusinessLogic.User(0));
                return newMember.Id.ToString();

    Umbraco version is 6.1.1. I didn't have this problem in 6.0.5.
