Installing Drupal

In modifying the xtemplate.xtmpl file to reorganize the tables, I'm getting a the error above. Unfortunately, Drupal.org's forum rules keeps terminating my attempts to paste the actual code here, citing 'suscipicious entry'. So I'm not quite sure how clear this will be without the code, but...

Reordering the tables in xtemplate.xtmpl gives me two errors:

parse: blockname [header.search_box] does not exist, and
parse: blockname [header.blocks] does not exist

Hello there :)
I'm totally new with Drupal and I'm going to install it.
But...I really can't understand how to do it...
The manual talks about commands like

GRANT ALL PRIVILEGES ON drupal.*
        TO nobody@localhost IDENTIFIED BY 'password';

.

But, where have they to be entered?

I haven't found any discussion on this:

Where is it possible to edit the template so that the username does not appear at the top of the navigation block?

(in other words, on this site, my username appears in bold grey immediately under the search box, above 'Create Content', etc. I would like to edit this behavior out of my own site.)

Hi all

I have installed drupal and changed in my conf.php the urls to my domain name, but when I now connect I get this error in my browser :(
any help?

Warning: mysql_connect(): Can't connect to MySQL server on 'flappy.is-a-geek.com' (115) in /var/www/includes/database.mysql.inc on line 12
Can't connect to MySQL server on 'flappy.is-a-geek.com' (115)

I have been reading INSTALL.txt and it gives very specific instructions for creating and configuring a db for drupal. My host only allows me to have one db and I have no control over the db name. Can I just skip the create db create step and the "GRANT ALL..." step and start with LOAD DB scheme?

Thanks,
Erik

When I installed drupal 4.4.2 on to a linux box it keeps throughing up this error:
Fatal error: DB Error: already exists query: INSERT INTO sessions (uid, sid, hostname, timestamp) values(0, '407edfd7e4249d7717a7bc81160c5ca0', '192.168.0.1', 1091354020) in /var/www/html/mike/includes/database.pear.inc on line 89

I'm using postgresql on the box.
Does this happen to anybody else?
If so how did you fix it?

Thanks
