Hi Hikacrew;

So I read you documentation about installing Falang,
and you mention that Falang must be installed first then Hikashop.

But as I already have a fully functional Hikashop site, and in order to install Falang first would mean
a whole lot of hassle, so I decided to try installing Falang over Hikashop ( on a test server of course).
And to my surprise, it works. Now I'm not 100% sure, but so far so good.
Everything in Hikashop has the translation option(product, categories, characteristics, etc...) & Joomla articles & menus too.
The only problem I have is with Advanced Module Manager (by regular labs) , but I have a feeling I can fix that.

So my question is:

Is it ok to have installed Falang over Hikashop or is there something going on in the background that I'm not knowing about?

Cheers

V.

Falang does not work with HIKAMARKET
to translate the category names in the insertion of products from frontend
