Mattew, thank for the prompt answer. In effects, for some reason the app was preset 2 times in the INSTALLED_APPS list, also if I am sure I added it only once at the beginning of the list. Maybe django added it again at the end of the list. I will watch this behavior and let the list know. Problem solved
