Can't create Brands

-- HikaShop version -- : 2.6.0 Starter
-- Joomla version -- : 3.4.8
-- PHP version -- : 5.5
-- Browser(s) name and version -- : Firefox 43.4

I installed the starter version and I can not create brands, I redirected to the category menu. I downloaded the installation package from the web this morning directly.

I tried to uninstall the store, delete tables database and reinstall the store. Keep going the same.

What's going on?

Hi,

I've tried on my end but I don't have the problem.
I also tried on our demo website and it works fine.
Are you able to reproduce on our demo website ?
What exacts steps do you do to reach that ?
