I changed the MySQL root pw to contain only alpha-numeric characters and re-installed. This time, I got the following output at the end of the install process:
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /root/ispconfig/scripts/lib/config.inc.php on line 47
No results found!FreshClam is already running!
ISPConfig system is now up and running!
Again, the database has been created, but there are no tables in the schema. When I attempt to log in to ISPConfig through the web interface, I get the message that the password (admin) is invalid.
