Hope someone can help me. I use the Onum theme a i think i am missing items in the customizer section like preloader. How can i get the other items back ?
check Appearance => Menus
there you should get all the already assigned menus. From those select one as primary/main menu.
Otherwise you can contact the theme author for technical query.
I am sorry i didnt mean the menu but the costumizer of the theme. I only have a couple options left.
There should be a section that where you can manage the theme options.
If it’s not there, probably you will need to manage it manually.
( Check the documentation )
You may require license activation to get more premium features/options. You should contact theme author.
