This maybe answered elsewhere but for anyone who needs it I managed to get it working by just changing the two config.php files in browser and upload to this.
global $Config ;
session_start();
// SECURITY: You must explicitelly enable this "uploader".
$Config['Enabled'] = true ;
$userpath = $_SESSION['kt_login_user'];
// Path to user files relative to the document root.
$Config['UserFilesPath'] = "/UserFiles/$userpath/";
global $Config ;
session_start();
// SECURITY: You must explicitelly enable this "uploader".
$Config['Enabled'] = true ;
$userpath = $_SESSION['kt_login_user'];
// Path to user files relative to the document root.
$Config['UserFilesPath'] = "/UserFiles/$userpath/";
