[quote author="markusr" date="1296274152"]I've been using 2.0 for quite sometime, but for some reason when installed the official version my site broke I'm thinking the problem must be my .htaccess file, because "url/signup" doesn't work but "url/index.php/signup" does. Even though ive removed index.php from my $config['index_page'] from my config file. Does anyone have any tips or an official 2.0 .htaccess file??[/quote]

I had the same problem, i solved it by removing a "?" from the htacces file. My final htaccess file looks like this:

Options FollowSymLinks
<IfModule mod_rewrite.c>
RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
ErrorDocument 404 /index.php
</IfModule>

Hello,

There are two things I don't understand:
1. What is the reasoning behind the split?
2. What's with the drivers? What's the difference between them and class interfaces, class abstraction, inheritance and aggregation? "Drivers are a special type of Library that has a parent class and any number of potential child classes" doesn't help, really.
