Lorro, you are right! I just overlooked the submenu with Inventory settings on Product Settings.

Thanks a lot for your help!

lorro, Unfortunately these fields don’t show up for me on this particular woocommerce installation.

Everything goes to default-ssl.

The .htaccess contains regular wordpress stuff:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

I am not sure about shared environment – I use the virtual private server where I have full access to all files.
