Hi

Umbraco :7.5.14 assembly: 1.0.6345.13057

Merchello: 2.5

Fasttrack: 2.5

I have an installation witch has been running for 3 weeks, suddenly i get this error:

ERROR Umbraco.Core.UmbracoApplicationBase - An unhandled exception occurred System.InvalidOperationException: An error occurred when trying to create a controller of type 'Merchello.FastTrack.Controllers.Membership.CustomerMembershipController'. Make sure that the controller has a parameterless public constructor. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object. at Merchello.FastTrack.Factories.FastTrackBillingAddressModelFactory..ctor() at Merchello.FastTrack.Controllers.Membership.CustomerMembershipController..ctor(NewMemberModelFactory`1 newMemberModelFactory) at Merchello.FastTrack.Controllers.Membership.CustomerMembershipController..ctor() --- End of inner exception stack trace ---

I think it is related to the database, somehow. If i switch the database with my local database it is working, and the other way round is it not working.

I cant save members in the Umbraco Backoffice. There are 6 members / merchello costumers for testing created.

I use the standard merchello / fasttrack costumer setup.

Is there any one who can come up with a hint.. :-)

Thanks
