Communauty_auth 404 not found

Hi,

i've installed community_auth as third party. It seems its working, i was able to create an admin account adn it's registering correctly on my user table.
in the documentation : you have to mention to enable hooks in config file. thats missing.

my problem is that i have a 404 not found when i go to /examples
here is my .htaccess file :
<IfModule mod_rewrite.c>

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f 

RewriteCond %{REQUEST_FILENAME} !-d 

RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

Can you help, thank you ?
