Q: I Made Wordpress Multisite. And Now Everything Doesn't Display Properly I installed Ubuntu 10.4 then I installed Bitnami LAMP stack then I installed bitnami wordpress module then I tried to make the site into a multisite by following these instructions: 
http://wiki.bitnami.org/Applications/BitNami_WordPress_Multisite#How_to_add_several_WordPress_Multisite_blogs_with_different_domains.3f
AND
http://wiki.bitnami.org/Applications/BitNami_WordPress_Multisite
I can elaborate if needed: I enabled multisite in my wp-config.php file. Then I created a network using the wordpress dashboard. I was given two blocks of text to copy and paste 1 block into my wp-config.php file and one into my .htaccess file. I did that and now I get this:
When I go to my mywebsite.com I get this (this was there before I switched to multisite):

If I go to mywebsite.com/wordpress I get this (this used to be a functioning wordpress theme):

If I click on "My Blog" it redirects to 1mywebsite.com (where the "1" came from I have no idea)
If I try to login by going to mywebsite.com/wordpress/wp-login I get this:

and if I enter my user and password it redirects me to mywebsite.com/wp-login.php and gives me "Not Found" The requested URL /wp-login.php was not found on this server.
NameVirtualHost *:80
    <VirtualHost *:80>
    DocumentRoot /opt/lampstack-5.3.16-0/apps/wordpress
    ServerName mywebsite.com
    ServerAlias www.mywebsite.com
</VirtualHost>


A: I don't have experience with bitnami so I don't know how it changes the apache configuration but I would say the problem is the domain mapping. 
mywebsite.com maps to lets say /var/www/mywebsite 
but your wordpress is installed in /var/www/mywebsite/wordpress 
so the  url to it isn't mywebsite.com but mywebsite.com/wordpress and when you login it redirects you to mywebsite.com/wp-login beacuse in the dashboard you set the site address as mywebsite.com and not mywebsite.com/wordpress.
I would say you have two options:
You can change the site address that you entered in dashboard throuhg mysql in table wp-options, the siteurl value (you can do that thorugh phpMyAdmin if it is installed on the machine)
or
Change the document root for mywebiste.com in you Virtual host to the directory where wordpress is installed (you just add /wordpress to the end) (VirtualHost examples if you're begginer with them)
