Installing Drupal

I have Drupal up and running on a Mac:

OS 10.4 / Apache/2.0.52 (Unix) PHP/4.3.9 DAV/2 Server at localhost Port 80 / Drupal 4.6.2

As far as I can tell - everything is in order except that emails that should be sent (during registration or password retrieval) do not arrive.

I made a copy of my site to work on offline, but it doesnt seem to like to work.

The files are all set up properly, the database imports just fine.

When I visit the site - with firefox, it doesnt spit out an error, or a white page. It simply leaves me at the page that I was at.

If I go into the database and into the "system" table and set "status" for the comments module to 0, it works - sort of. I can browse the site, everythign comes up, exept of course comments, and I still get the non-response when I try to view the module or theme administration.

I've installed and configured my gallery2 beta3 installation on my site, and uploaded the gallery.module to modules, however, when i choose administer - blocks and select Gallery Image and Gallery Navigation it breaks my site, I get this error:

I thought the problem might be with my admin login so I saw on here where someone else fixed their problems by changing the uid of a user to the 1, so I did that, added another user, then deleted my admin user entry in my table of USERS, and then changed the uid of the new entry to 1. Nothing worked. So then I deleted ALL users except the UID of 0 from my USERS directory because I thought it would let me log in from start as first user is admin, and again, NOTHING, I cannot log in to fix the first problem.

Can anyone please check this out. I would be most grateful :)
I am just at the beginning of this drupal trip. My database is set up.
I go to http://girls.digitalgirls.org/drupal-4.6.1/ and I get this:

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /home/.nape/digitalgirl/girls.digitalgirls.org/drupal-4.6.1/index.php:1) in /home/.nape/digitalgirl/girls.digitalgirls.org/drupal-4.6.1/includes/session.inc on line 10

After that is the Drupal login page w/o styles, etc. If I try to "create the first account" I am taken to my site root: girls.digitalgirls.org

I am curious about the part that says .nape/digitalgirl/girls. as "digitalgirl" is the master site username (but not the database username)

I saw a forum post with the same error msg and the suggestion that spaces or random characters were stuck in the settings.php, so I opened a new settings file in bbedit and uploaded it. These are my settings:

$db_url = "mysql://myname:mypasswrd@dru.girls.digitalgirls.org/drupalDB";
$base_url = "http://www.girls.digitalgirls.org";

ANd my site info:

DB Name: drupal4grls
host dru.girls.digitalgirls.org
name: myname
pass: mypasswrd

ANy ideas where I have gone astray? I suspect perhaps there is some issue with the sub-domain?
I really appreciate. It is hot hot hot in Montreal today and my brain is frying :)

I've updated something and now can't log in with my admin account, I get this error:
