Problem mit Fanseite!

Hallo liebe Leute.

Ich habe vor eine Fanseite zu erstellen.
Habe bereits alles Hochgeladen, das CMS in FileZilla und die Datenbank bei phpMyAdmin.
Doch wenn ich meine Seite aufrufe kommt folgender Text:

Fatal error: Could not connect Database! in /users/retrohome/www/files/mysql.php on line 24

Habe bereits die config.php eingestellt.
Doch was muss ich tun damit es klappt?

Wäre erfreut über Antowrten.

Mit freundlichen Grüßen
Remind

Also ich benutze das CMS von PixelBeats.eu was Releaset wurde.
