I found - during my tests - a way - but you will LOOSE all users (must be added again; they keep their files):
1. Backup you configuration - especially of your users.
2. Make sure you're the only one who can access your ownCloud-Server (IP rules, etc)!
3. Edit config.php, set
- Code: Select all
"installed" => false,
4. Open ownCloud, set MySQL up
5. Register all of your users
6. Make your ownCloud available again.
