Cannot select categories on product view

-- HikaShop version -- : 2.6.4
-- Joomla version -- : 3.6.2
-- PHP version -- : 5.6
-- Browser(s) name and version -- : FF

I've created a couple of categories. Bur when I create an article I can only select the product root folder. Al the other categories will not show up. In the inspection windows I see an error probably related to this problem. On the product windows screenshot I also included the inspector view. I hope you can provide me with a solution...!

Hi,

If you take a look at your browser console, you can see the result of the ajax calls.
I don't know why your server display warning messages, but that warning is displayed at the beginning of the JSON : That's why the javascript cannot decode the json and do not display the sub categories.

To fix the warning (patch already ready in HikaShop), you can replace in the line 1315 of your HikaShop helper By
But I will also recommend you to not display PHP warning in your webpages.
The display of such information should be done only under development context. It is more than recommend to turn it off for production websites.

Regards,

Thanks for the support! Problem solved!
