Hi! It’s difficult to help without more facts…
You are talking about product. Is it means WooCommerce? It uses own templates and there is no pagination between products by default. So, this pagination can be in your theme and in this theme will be used hook to place this products links in right place.
For instance, StoreFront, “native” theme for WC has this feature and it is hooked like this:
add_action( ‘woocommerce_after_single_product_summary’, ‘storefront_single_product_pagination’, 30 );
And “woocommerce_after_single_product_summary” hook is a part of content-single-product.php.
This file can be in your theme, usually in woocommerce folder, if the theme overrides it or in woocommerce plugin subfolder “templates”. There is no need to change anything in plugin folders.
To unhook StoreFront’s hook, it needs to add:
remove_action( ‘woocommerce_after_single_product_summary’, ‘storefront_single_product_pagination’, 30 );
in functions.php of your theme or child theme if it exists.
If there is no custom modification in your theme, don’t change it now to keep availability to update it. Make a Child theme, if you don’t have it, and in its functions.php unhook what you need.
Sorry for too late reply. After my question I had to give this task to someone. I just noticed your reply. Thank you for that.
