Missing menu-items in backend

-- HikaShop version -- : 2.6.0
-- Joomla version -- : 3.4.4
-- PHP version -- : 5.5.26
-- Browser(s) name and version -- : Firefox 40

In backend I miss the sub menu items Display > Content menus and Display > Content Items. I can only View and Custom Fields.

What could be wrong, and how can I correct this?

Hi,

As it states in the changelog:

The HikaShop options for the menus are now editable in the Joomla interface. The HikaShop options for the modules are now editable in the Joomla interface.

So, use the Joomla menu items and modules to edit HikaShop settings.
