Sorry, I missed a line.
The whole code block should be:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /your-wordpress-folder/
RewriteRule ^index\\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /your-wordpress-folder/index.php [L]
</IfModule>
