'BlogConfigWithAppDataForm' object has no attribute 'label_suffix'

I performed a clean installation of django-cms (latest-3.7.2) and later djangocms-blog (1.10). It is weird that the AutoSetup does not perform, so I run it manually.

When I try to add BlogConfig, here is the error I found while rendering template. Tried to check where is BlogConfigWithAppDataForm. It is no where, unfortunately.

Request Method	GET
Request URL	http://localhost:8000/en/admin/djangocms_blog/blogconfig/add/
Django Version	3.0.6
Exception Type	AttributeError
Exception Value	‘BlogConfigWithAppDataForm’ object has no attribute ‘label_suffix’
Exception Location	/Users/atlonxp/anaconda3/envs/iba-website/lib/python3.7/site-packages/django/contrib/admin/helpers.py in label_tag, line 190

**Error during template rendering** In template /Users/atlonxp/anaconda3/envs/iba-website/lib/python3.7/site-packages/django/contrib/admin/templates/admin/includes/fieldset.html, error at line 15

At line 15, the statement is {{ field.label_tag }} but error said 'BlogConfigWithAppDataForm' object has no attribute 'label_suffix'

so weird!.

Does anyone has this problem before?

@yakky migrate to Django 2.2.12, it works smoothly BlogConfig can be done manually.

@atlonxp I traced the AttributeError down to this PR https://github.com/ella/django-appdata/pull/23 (which I opened myself 😄 ) which is awaiting review I will add a note on the readme regarding django 3 support, for now
