Update to 8.6 and Display setup in admin theme options disapeared

Hi,

I just update my theme to 8.6 and my admin menu sidebar is now different.

In theme options i don’t get display setup option in my admin board,so i can’t change anything in my homepage to have,for example my feature listing in the slider or on the homepage like in the previous version.

Some people paid for that and i don’t want to unsatisfied them.

If somenone know what i can do,it would be really appreciated. 🙂

Thank you,
Have a nice day.
