Drupal 6.x

I just set up a multisite installation with Drupal 6, and everything seems to be working fine except that it says CLEAN URLS are not configurable for the add on sites. The strange thing is that it is letting me run clean urls on the default site. Does anyone know why this would be, or what I could do? I know that Apache is set up for it--it is already doing it! What are the possible factors that would make it not let me run clean urls?

hello everyone. i'm new to drupal. i am wondering what modules do i need if i want to make a sort of library for books using drupal.. users can view the the books owned by another user. they can review it, upload pics of the book, add some info on the book, search, etc... any suggestion is appreciated. thanks!

So I thought I'd give Drupal 6 a spin on MAMP. I have Drupal 5, Wordpress, etc, etc all running but can't seem to get Drupal 6 up.

I use phpMyAdmin to make a database and user, then go to my directory and unpack drupal 6... it all shows up fine. But right after the page where I enter my database name, etc and hit continue I just get a blank screen. Just white. Nothing. I reload, etc but nothing.

I'm frustrated.

Does anyone have any suggestions? Is there something I need to do for mySQLi databases as opposed to mySQL databases?

Please help, I've tried to figure it out whole day, but failed....The second installation step, setting DB name and user-name.
Fatal error:in ..\includes\database.mysqli.inc on line 135
