How to fix Atribute Error: 'NoneType' object has no attribute 'strip' error when creating page in django-cms?

Question

MySQL

I am new to Python and Django, however, the task arose to deploy a web portal on Django-cms on a local machine (using OpenServer). The installation went through no less a lot of rake and yet after installation I tried to create a completely blank page (without any code) and the following error popped up after clicking "Save":
AttributeError at /en/admin/cms/page/add/
' NoneType' object has no attribute 'strip'
Request Method: POST
Request URL: 127.0.0.1:8000/en/admin/cms/page/add/?language=en
Django Version: 1.7.7
Exception Type: AttributeError
Exception Value:
' NoneType' object has no attribute 'strip'
Exception Location: C:\Python27\lib\site-packages\mysql\connector\cursor.py in statement, line 860

A lot of googling didn't turn up a solution, and dirty hacks (like commenting out this exception in cursor.py) led to other errors. Help, please, to understand.

Answer 1

Probably not specified settings for the database.
For example:
