Hi, And thanks for what seems to be a very useful plugin.

I get a 'NoneType' object is not iterable type error when trying to add a section container:

Hello, I have the same problem when adding a section container (my versions: django 1.8.12, djangocms 3.2.3), thank you

@Atterratio I ended up writing my own plugin in the end.. @marcelox You need to add an if statement before the 2 for loops inside cmsplugins.py to make sure instance.child_plugin_instances is not None, so it doesn't try to iterate when there are no sections in the container yet. It is fixed already in one of the branches I believe.
