Installing Drupal

I just did a fresh installation and tried creating and then deleting a user.
To delete the user I am going to "admin/user", clicking on the edit link and then clicking on the Delete button at the bottom of the user form. After I click on the Delete button the "admin/user" page is displayed again, and the user I just deleted is still there. No errors or warnings in the log.
If I go to "user/3/delete" (user id 3, for example) I get the "Are you sure you want to delete..." page and clicking Delete there does the trick and the user is removed.

Any ideas?

user error: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1
query: SELECT i.* FROM aggregator_category_item ci LEFT JOIN aggregator_item i ON ci.iid = i.iid WHERE ci.cid = 0 ORDER BY i.timestamp DESC, i.iid DESC LIMIT 0, in /home/riotboar/public_html/cfb/includes/database.mysql.inc on line 125.

This started happening when I began removing categories wthin news aggregator.
Any thoughts?

Currently I'm testing out/configuring drupal on my site in a subdirectory, while my old site stays in the root of my html directory.
Is there an easy way to move drupal so the index is in the /home/me/html directory, while all the other files stay in /home/me/html/drupal?

Sorry if this is answered in another post, but I couldn't seem to find it.

I'm getting this daiily in my log and its confusing - because I'm on a Linux box.

scripts/..\\../winnt/system32/cmd.exe not found.

I'm also seeing a log error to a call in my /cgi - one of the stat files

I've never seen these errors before upgrading to 4.6

is someone "Anonymous" ... trying to hack me ... and because of some new improvement to 4.6 --- I'm being advised?

thanks

It's total useless with Postgresql database.

I can't make any new story/page... with normal user:

warning: pg_query(): Query failed: ERROR: invalid input syntax for integer: "" in /var/www/linux.oregpreshaz.hu/docs/includes/database.pgsql.inc on line 45.

I was wondering if I could get a few examples of what you guys are using here. It would be very helpful.

e.g.

• files/private
• ../private
• /home/httpd/vhosts/domain/httpdocs/files/private
• etc.
