Installing Drupal

Another newbie here! I have installed Drupal on my server which is running PHP 5 and mysql. It seems like a fairly straightfoward install, and I didn't have any problems following the instructions. However, when I point my browser, I get many messages...the first of which is...

Drupal installation instructions are inadequate and confusing. After reading the instruction a doze times, this is what I undestand

I am trying to set up Drupal on a new site. I have it set up but with some problems.

The setup is on www.abusedhusbands.org; it works fine and brings the user to the index.php page just fine. But abusedhusbands.org on the other hand gives a MySQL error. abusedhusbands.org/index.php works fine also.

So, where am I going wrong?

I had installed drupal in a subdirectory to build the test site. No hitches, I edited the .htaccess file (uncommented the rewrite line like it says) and had no problems enabling the clean url feature. It was a thing of beauty.

Help me please.
When I go to My admin link i have this repeating error with weblink
here is the first error with my dbname removed;

error php 2005-08-18 07:37 Table 'xxxxxxxx.weblink' doesn't exist query: SELECT n.nid, n.tit

and here is the detail of the error;

when I go to install drupal i already am using a table in my database called users, I could rename the new (drupal) users table to drupalusers, but I am worried that not only will I have to searh through the main program and change all the table references, but that new modules will also need to be changed. Nightmare.

I am going to think about changing the table users that I have already been using to another name.
