I'm still planing to move to a 2.18.5, I've already installed it but in the
welcome/modules folder there's only the __init__.py file, it's an empty
file.
>The module 'six' is a compatibility layer between API of python2 and

That could be the problem.
>I cannot see now why it should be in your apps module dir...
I've got __init__.py and pyc, api_site.pyc, plugin_ckeditor.py and pyc.
