If somebody have a idea, thank you.

Solution

Remove this line from your settings:

from django.conf.global_settings import TEMPLATE_CONTEXT_PROCESSORS as TCP

TEMPLATE_CONTEXT_PROCESSORS was deprecated in Django 1.8 and removed in Django 1.10. It's not possible to import it anymore.

You have already defined context_processors in your TEMPLATES setting, so you don't need TEMPLATE_CONTEXT_PROCESSORS anymore.

[Alex Hall]

How should TEMPLATE_CONTEXT_PROCESSORS = TCP + (... be migrated in 1.10? Should the defaults just be included manually? Are there even defaults any more?

[Alasdair]

@AlexHall When you create a new project in Django 1.10, it uses this template by default. However, you can't import this list easily, because it's a template file not Python. I suggest that you simply list the context processors in your TEMPLATES setting, rather than trying to do anything clever. Perhaps you'll get different suggestions on your new question.
