Hello, Namaste,
Thank you for your response.
“how can I fix it?” – please provide temporary wp-admin access, so we can take a closer look at the settings on your site.
“Also how can I define number of rows?” – it calculates automatically, based on columns and the products limit you set.
“How can I add widgets so I mimic category page with filters etc on the left sidebar?” – there is no such possibility because WooCommerce widgets work only for WC pages (Shop, page of category, or brand).
Kind Regards,
8theme team
