Nextcloud version: 15.0.2
Operating system and version: Ubuntu 16.04
The problem is very simple, the machine ran out of disk space and for some reason nextcloud cleared config.php. Now it’s asking me to reconfigure but I’ve got a whole bunch of documents etc, existing accounts, data configs etc already existing.
How do I configure Nextcloud to use the existing database connection with all the existing files and user accounts etc?
