Hi,
I encountered the exact same problem as you. A issue on the github repo seems to have a solution: After reset, News App is not working · Issue #838 · nextcloud/news · GitHub.
Perform the following steps:
- Disable and remove news app
- Remove all settings in the db: DELETE FROM oc_appconfig WHERE appid = ‘news’;
- Remove all migrations in the db: DELETE FROM oc_migrations WHERE app = ‘news’;
- Reinstall and Enable news app.
Caution: Please be careful when tinkering with the db and always perform a backup beforehand.
