I was on an old version of Nextcloud (Version 14) and so I started using the web updater to update as far as I could go. Everything was going well until I upgraded to 18. Now, my login page, settings and user data is now missing. After frantically ssh'ing into the server, I found that all my files are still there, including my config file was not touched. It seems that maybe either a compatibility with the database I was using broke and it created a new but empty database.
How can I fix this? I hope to go to version 23.
