Nu sunt foarte familiar cu .htaccess-ul Redenumeste htaccess.txt in .htaccess
In el incearca sa pui codul. Eu am asa pentru un site facut cu wordpress:

Cod:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
