no more data, but still working

[globul69]

Hi,

To correct a "bad gateway" error, I modified these parameters in docker-compose.yml :
initial : - ./data/mysql:/var/lib/mysql
new : - ./mysql:/var/lib/mysql

Since then, I have been able to connect with the following logins:
Email: admin@example.com
Password: changeme

Everything works normally (certificates, redirection...) but I don't have any configuration available!
even if I look at the tables in mysql, they're empty?
