Hello, I'm upgrading a friend's blog, she was stuck with WP 2.9.2 and Eshop 4.1.0, she never dared do the updates herself, it's been... quite a while already.
While WP upgraded itself smoothly, to my relative lack of surprise, upgrading Eshop from 4.1.0 to 6.3.3 apparently broke the plugin, or part of it at least.
The website is cactusargan.com, and one of the product pages is : http://www.cactusargan.com/?page_id=3675
(You'll see a working sales page, I restored a backup with already WP3.5 but still Eshop 4.1.0's files and database)
Simply, when opening a page with a product on sale, there isn't a single mention anymore of commercial operations : price, stock, adding to cart. Only remains a "0 items in the basket" in the top of sidebar.
Frankly, if it were a small upgrade between two close versions, I'd have known where to search, but, here, Jebus, I don't have a single clue. I can't reinstall from scratch, the website already has a product and consumer base.
Please, would you know, maybe, where I could start, or how, to find how to fix that issue ?
Thank you :)
