Hi All,
in a checkout page, if i click the product link, the system reply me with this error:

"1054 Unknown column 'product' in 'where clause' SQL=SELECT category_id FROM vd2ur_hikashop_category WHERE (category_access = 'all' OR category_access LIKE '%,2,%') AND category_type='product' AND category_id IN (product)"

Why?
Product is correctly on line, and if i try to pay it's work!

Please help me!!!

And

Hi,

I do not have the problem on my end. The link to the product page ( photostore.andreasuriani.com/index.php/p.../1-ti-amo-biscottino ) works fine.

Hi Nicolas,
no, it's wrong.

Try to add this product on cart,
after, from payment page, try to click on product link.

The link in a payment page is ( photostore.andreasuriani.com/index.php/p.../2-ti-amo-biscottino ) and not (photostore.andreasuriani.com/index.php/p.../1-ti-amo-biscottino).

Why??

Hi,
Can you turn on the "debug mode" and "error reporting" options of the joomla configuration and try again ?
The error message should provide more information on the issue which will help us identify the problem.

Hi Nicolas,
i did it.

Can you check the error?

Hi,

That doesn't give more information and I can't reproduce the problem on my end.
Could you provide a FTP access to your website via our contact form with a link to this thread so that we can look deeper into the matter ?
