Can you reproduce this issue on default Wordpress theme (eg Storefront)?

Can you reproduce this issue when all other plugins are disabled except WooCommerce, Polylang and Hyyan WooCommerce Polylang Integration?

What product versions and settings are you using when this issue occurs?

• PHP: 7.1.18
• WordPress: WordPress 4.9.6
• WooCommerce: 3.4.2
• Polylang: [state if using Polylang PRO]: 2.3.7 [No pro version]
• Hyyan WooCommerce Polylang Integration: 1.2.0
• Browser: Opera, Chrome.

Maybe there is a problem with your permalinks?
Try going to Settings, Permalinks, set actual values, especially for Product Permalinks - I use something like /p/%product_cat%/ and Save.
The Permalinks should then be set.
(the permalink part is not translated and can cause problems if not set)
