I have transfer a Joomla site to WP. The products and everything are imported right. The comments are not displayed.
In the db I can see the comments wp_comments
Here is an example
ex. http://makan.gr/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=784&category_id=233&option=com_virtuemart&Itemid=1&lang=en has comment
http://www.suco.gr/makan/wp/product/bmw-r-1200-gs-adventure-crash-bar-bags-1-pair/ don’t have comments.
The fredericgilles.net which create the import tool told me that it is theme issue.
Can you see that and please let me know why I can’t see the comments?
