Post installation

I'd like to know what file actually generates the "page not found" so that I may add some additional text to it. Does anyone know?

Hi,

I want to redirect users to a splash page similar to the front page module. The problem is how to automatically send them to the current home page from the splash page without having to click on a link. Using

When using the Edit>Items feature as an administrator in the store, I keep getting there error:

user warning: Duplicate entry '0-0' for key 1 query: INSERT INTO ec_transaction_product () VALUES() in /var/www/html/drupal-folder/includes/database.mysql.inc on line 120.

Is there a known problem with this feature, or have I managed to mess something up?

Also (a perhaps related problem, in that it's also dealing with the ec_transaction_product table, when I click the "x items" link when page that allows you to view all open transactions:

If you click that link, you will see a little pulldown menu at the top catagory that I accidently exposed....how do I get rid of that? Any help would be GREATLY appreciated...

I have never dealt with CMS software before. I have wordpress set up on my personal site, and I help run a phpBB forum with Gallery. So I'm only used to single content type sites...

I am changing a web site for my camera club. I saw this site: http://lacrosseareacameraclub.org/

I think this is the way to go for us as well. I like the way it's laid out and it would be easier to keep up to date...

I had been messing with Drupal a lot until yesterday I accidentally run my drupal site under offline mode and then logged out. Now everytime I access my site the offline page appears with no place visible for me to log in and reenable the site.
Is there any way I can log in as an administrator now?
Thanks.
