[sitnarf]

Steps to reproduce

1. Enable "Versions" app
2. Create Test.md in files
3. Edit it several times over few minutes

Expected behaviour

In the sidebar, under Versions, several versions should be available

Actual behaviour

In the sidebar: "No other versions available"

Additional info

When files_versions folder checked, versions are not created. There is a possibly related error in the log (Call to undefined method OC_DB::getDbStructure()).

[solracsf]

The error Call to undefined method OC_DB::getDbStructure() seems related to https://github.com/pbek/nextbackup not to Nextcloud core.

[joshtrichards]

Indeed. That third-party app never supporedt >=NC22: pbek/nextbackup#51

This old Issue needs to be closed out.
