After a few weeks without accessing the instance I installed on my own storage through ftp, I tried to log in only to realise that my (superuser) account was disabled, which shouldnt be possible according to the doc (https://docs.filerun.com/admin_guide#superuser). I then found out that the free version I was using (limited to 3 accounts) is no longer offered (and replaced with a 99€/year subscription).
I suspect this is why I was locked out of my own instance.
I get that the dev behind the software is free to do whatever they please with their software, and I just have to go back to using owncloud but this is not a pleasant experience.
Was anyone else bitten by this ?
