[Django]-Error with aldryn_bootstrap3: Field defines a relation with model '…', which is either not installed, or is abstract

✅

Aldryn Bootstrap3 depends on django-filer. You should install it first:

INSTALLED_APPS = [
    ...
    'filer',
    'mptt',
    'easy_thumbnails',
    ...
]

The errors you are getting (Field defines a relation with model ‘File’, which is either not installed, or is abstract) are telling you that some models depend on other models that Django cannot find.

Specifically, in this case, Aldryn Bootstrap3 models depend on the models File, Image and Folder that are defined in django-filer.
