It's looking for a settings.CMS_TEMPLATES. It's trying to make None a tuple which would throw that error.

Make sure you have a CMS_TEMPLATES defined.

http://docs.django-cms.org/en/2.1.3/getting_started/tutorial.html#configuration-and-setup

Your CMS_TEMPLATES settings is None, I have no idea what that is, but I'm guessing it a setting you need to configure somewhere.

settings.CMS_TEMPLATES is None, I believe. It's hard to tell without a sample of the code in question.

Referring to edit 1:

Which commands are you using? Are you following the tutorial? I guess you did not do:

python manage.py syncdb

If you just wrote your models, this command will create the tables in the db. Otherwise the database is empty, which is the reason why Django can't find the cms_pagetable.
