Only default controller is working

Hi everyone!
From years I've been using CodeIgniter 2 and it's very well.
Yesterday I started a new project with PHP 7 and I read it's better to use CodeIgniter 3. 
I installed CodeIgniter 3 but is loading the default controller always, but the others controllers doesn't work....

I changed my htacces but doesn't work....
<IfModule mod_rewrite.c>
RewriteEngine On

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


Has Anyone an idea? Thanks.
