Hello there!

While creating a news & blog in LTS releases, I'm getting this error. Not
sure what could be the possible reason.

RegistrationError at /en/cms_wizard/create/

<class 'cms.models.placeholdermodel.Placeholder'> has not been registered with django-reversion

Request Method: POST
Request URL: http://127.0.0.1:8000/en/cms_wizard/create/
Django Version: 1.8.15
Exception Type: RegistrationError
Exception Value:

<class 'cms.models.placeholdermodel.Placeholder'> has not been registered with django-reversion


Thank you.

Sunil

Can you try removing reversion from INSTALLED_APPS?

I just had the same issue and found it was because 'reversion' *wasn't*
listed in INSTALLED_APPS.

I had used the djangocms-installer to create a blank CMS project and then
followed the aldryn-events installation instructions. I think the two are
slightly out of sync.

I hope this helps.
