Looks like migrations weren't run. A couple of people have reported this, its just that they didn't run migrations.

[shadow-identity]

I've done migrate. But now it returns on both (clean and updated) installations:

  No migrations to apply.
  Your models have changes that are not yet reflected in a migration, and so won't be applied.
  Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.

I didn't change anything manually. After makemigrations I've got those migrations:

Migrations for 'filer':
  0002_auto_20150422_0048.py:
    - Alter field polymorphic_ctype on file
Migrations for 'aldryn_categories':
  0004_auto_20150422_0048.py:
    - Change Meta options on categorytranslation
    - Alter field language_code on categorytranslation
Migrations for 'aldryn_people':
  0003_auto_20150422_0048.py:
    - Change Meta options on grouptranslation
    - Change Meta options on persontranslation
    - Alter field language_code on grouptranslation
    - Alter field people on peopleplugin
    - Alter field language_code on persontranslation

[mkoistinen]

Oh! Looks like we don't have 1.7 migrations. =( Will fix soon.

[shadow-identity]

Yep, supporting both South and Django migrations is a pain.

[mkoistinen]

@shadow-identity Please try 0.9.3. This should have the migration you need. =)

[shadow-identity]

@mkoistinen nope, it is still here...

And boilerplates issue is still here. Can you accept aldryn-boilerplates#7?
Without it boilerplates fails:

Can you try 0.9.4?

[shadow-identity]

I've updated installation to aldryn-boilerplates-0.7 aldryn-common-0.1.3 aldryn-newsblog-0.9.4 aldryn-people-0.5.2 django-taggit-0.14.0 lxml-3.4.4

Now all works fine, thanks!
