Guestbook - Connection error

after creating the DB tables I used the link
Click now here to setup the guestbook admin...
/guestbook/admin.php

And got these errors:

Warning: Access denied for user: 'root@localhost' (Using password: NO) in ................/guestbook/lib/mysql.class.php on line 30

Warning: MySQL Connection Failed: Access denied for user: 'root@localhost' (Using password: NO) in ................/guestbook/lib/mysql.class.php on line 30
Connection Error

Does anybody have an idea how to solve this problem?
Thanks a lot

I had the same.

Open up config.inc.php and amend the database settings at the top:

/* database settings */

$GB_DB["dbName"] = "name of database";
$GB_DB["host"] = "localhost";
$GB_DB["user"] = "your user name";
$GB_DB["pass"] = "password";

(modify the red bits)

Save and upload

thanks - being new to php your mail help a lot
