I've tried everything but still not working. The log:
[ERROR] The SQL server seems to be down [Access denied for user 'root'@'localhost' (usi
ng password: YES)]
And yes, mysql is working. pure-ftpd tries to access database with 'root' user, while it should be using 'ispconfig'?
I don't know what else to do, reinstalling doesn't seems to change anything.
