HI,
The comparison is not exact. You sell a web product and when i buy it, i want that this product run perfectly.
You are not able to make a product with multi language support. This is the problem.
New Joomla Version, doesn't need any plugin to run with multi language. (In the past, they've needed it) So, why you can't do the same?
Anyway, if can help me, i will thank you.
In order to response on your question, the FaLang version is the latest. (Like Hikashop)
(Now, i'm not able to open my website because my provider doing an urgent maintenance: it will be finish tomorrow morning)
Regards
Andrea
