Shop installation inside WordPress directory

Hello, I’m trying to install magento inside wordpress directory. I’ve created a directory named /shop so the path is /wordpress/shop/ But when i try to access it i get the 404 error not found from wordpress. I guess this is a matter of htaccess but i can’t find a solution so it can let me access that directory.

here is my htaccess

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

# END WordPress
