Hey @elchavodel8,
Hope you’re well.
MarketPress force to keep comments closed so only adding comments_template function will not work. You can change that from wordpress-ecommerce/includes/public/class-mp-public.php file 134.line, there is function which name is disable_comments_on_store_pages. Replace that function content with this function content;
public function disable_comments_on_store_pages( $open, $post_id ) {
if( $this->page_in_store_pages( $post_id ) ){
$open = false;
}
if (get_post_type($post_id) == 'product'){
$open = true;
}
return $open;
}
Then it will start to show comments on product pages. But keep in mind this is not absolute solution your changes will be reverted once plugin updated.
Cheers,
Oguz
