Problems with installation over existing wagtail and multilanguage

[jmponce84]

Hi.

I'm trying to install Puput on an existing installation of Wagtail with multilanguage. However, I'm having problems once I try to run the migrations:

Traceback (most recent call last):

Any suggestion on how this can be sorted?

Thank you very much in advance!

Ok, I think I sorted it. In the translation.py file is just a matter of importing BlogPage with from puput.models import BlogPage and then adding the desired fields to be translated as usual. Or at least this is how I believe is sorted...

Wow, @jmponce84 ! Great moves. Keep it up!
