I use the theme and I have two problems.

First, product pages with accessories, the theme does not work there is no layout . There is simply information and pictures. Quan I withdraw accessories it works .

Second problem : when I want to use on the home page of the “products tabs slider”. I can not add or remove a product category. There is always the same category of product, impossible to choose something else. I tried with safari and firefox but the changes are not taken into account.
I try to reset the module without any changes.

I use prestashop 1.6.1.4
