Hi Sören

Not sure what the error is all about but I'm wondering if it might be worth trying to upgrade to 7.1.3 and see if the issue persists?

Hi Jan,

I have upgrade to 7.1.3, but the issue exist now.

I have now install a clean 7.1.3 and it works great. But in my old upgraded instance it doesn't works. Looks like an issue in my old instance. I check this again...

The same issue exist again!

I have create the following simple eventhandler:

public class Eventhandler : ApplicationEventHandler
    {
        public Eventhandler()
        {
            MemberService.Created += MemberService_Created;
        }

        void MemberService_Created(IMemberService sender, NewEventArgs<IMember> e)
        {
            IMemberService memberService = ApplicationContext.Current.Services.MemberService;
            string code = Guid.NewGuid().ToString();
            e.Entity.SetValue("activationCode", code);
            memberService.Save(e.Entity);
       }
    }

It works great at first time. But if I register a second Member I get the exact error message from my first post above. Before I create the Eventhandler, I have register a lot of Members without problems. If I delete the eventhandler in my project, compile the project again and copy the project-dll without the eventhandler code in the bin folder, I get the error message still. I have recycle AppPool and clear the cache of browser, but nothing works. This is the same issue like 5 days ago.

And now, after I log in to umbraco I see a white clean page without backend. Umbraco is crashed... But the frontend works...

Ok, something is wrong with my umbraco instance. Just do not understand it....I tested this with a new clean umbraco instance, now. And it works in this every time. Now, I use the new clean umbraco instance and delete the old...

is working on a reply...
