Editing Shop Details

I tried to change the shop name and currency. But anytime I save it says “unable to load user with id:42” and the new changes are not applied. I installed the template through wamp. I have had this issue with the Ecomerce template its only the Book store templates that works perfectly.. please how can I ratify this issue on the Hot Furniture Store Template.thank you
