Hello,

Please disable the custom template as shown on the screen: https://gyazo.com/2d36b1d6e765d47b191ee719383312b1

Then make the full backup of your site and check the issue on the Storefront theme to detect if our theme causes the problem. Storefront is a free theme developed by WooСommerce.

If you see the same, please set Woocommerce pages as described here: https://woocommerce.com/document/woocommerce-pages/

Best Regards
