You can changee the username in the database at the table 'faucet_settings' at the row number 12, it has the name 'admin_username'.

You must upload zip to your server (file manager) and extract all files there.
Then you will go to your phpmyadmin and import sql file there.
Thank you, that worked. Used Filezilla to upload the files and phpmyadmin for the sql.sql.
i managed to configure the faucet but now i got some questions:
1.Next to the starting page of my website there is an extra tab called Faucet which is basically the same page...how can i remove this?
2. Even though i changed the faucetname it is still shown as Demo Faucet---see the picture i attached.
3. how do i add satoshis to the balance?
4. i added 3 ads from adsense but i cant see them...does it need some time til they are visible?
-snip-Thanks for your help so far

1. Replace in 'includes/templates.settings' the code
$navLinks = [["Faucet", "index.php"]]; to
$navLinks = [];2. You can change the Name in the admin.php or in the database in the table 'faucet_settings'.
3. Fill your Faucetbox.com Balance. Go to Faucetbox.com and deposit some Satoshis.
4. Is your adsense account approved? If not, it will show a white screen.
Cheers
