If you added djangocms-versioning to an existing project you should try this management command:

python -m manage create_versions --username <someusername>

When djangocms-versioning is installed, it keeps track of the status of pages and other objects by adding a version object t to them. This is done automatically, but for your existing objects you will need to create versions objects.
