Post installation

I have installed Drupal 4.7.0 beta3 on a XAMPP server. Everything went OK until I logged out then when I tried to get back in I get the message below:

"The username has been blocked"

Btw, the Who's Online teels me I'm online with about 10 guests ???!!! (localhost installation)

HELP ME!!!!!!!

I just installed drupal and have launched a website. I am using one user, admin, to to all the administrative work, and another user to submit stories, etc. So I was submitting a story and realized I was in admin acct, so I logged out of admin and logged into the other one and submitted the story. Now on the front page, it says admin submitted the story, but it says in the watchdog that the other user submitted the story. I was using the opera browser, and also have noticed strange caching behavior. When I log into admin, it still displays the other user's menu, even after I refresh.

The content types created with the flexinode module do not work togehter with the excerpt module. It does not save the text entered in the textarea for the excerpt, instead the first paragraph of the textarea of the content is saved as excerpt.

Did someone already detect where the mistake ist?

I'd like to hide the Nav Menu block until a user logs in. spreadfirefox.com appears to work this way--it displays the login block until someone logs in, then it swaps the login block out for the nav menu block. I'm currently using the latest version of CivicSpace, which is based off of Drupal 4.5.

i've enabled simplenews in my drupal and then i got this error...

user error: Table 'site.sn_newsletters' doesn't exist

by the way i'm using my home server not webserver...

how to get over this error?

do you know a way to make the user able to invite his friends by sending them emails to a drupal site?

thank you :)
