Hello

My problem is when it come to the part of ADMIN name and password - I don't know what to write, I have been looking at the various pages, hoping to find a default name and password, but without success.

You have to set the username and the password for admin yourself during install process.

Same problem with the part of DATABASE name, user and password.
As mentioned, I'm new to PHP/MYSQL so please have patience with me as I'm more than willing to learn (but have to start somewheree)
I'm running a small homepage on my own PC connected to a NAS Synologi DS207+.

You need a web server with PHP and MySQL. You need a configured MySQL database. While configuring the database you'll set a database name, a user name and a password. These data are needed for the installation of mlf.

Tschö, Auge
