menu configuration disappears

-- HikaShop version -- : 2.6.3
-- Joomla version -- : 3.6

Hi,

when I create a new menu, as long as I choose "hikashop product or category", then the menu configuration disappears.

while I choose the rest options, everything is just fine, why? I'm really really confused.

Hello,
That's actually weird, when I test it on my end the configuration menu is still displayed, can you :
- Activate the Joomla debug mode ("Administration->Global configuration->System->Debug System/Language")
- Set the "error reporting" option of the Joomla configuration to "maximum"
- Test it again so that you can see if it display an error message which will help you to understand from what your issue is coming.
