I am continuing to try to find a solution to this problem. I deactivated all plugins except GP Premium. I thought perhaps the links weren’t showing up because they were “forums” instead of pages, so first I tried putting just one custom link in the “Forums” secondary menu. It still shows a duplicate of the primary menu.
Next, again with all plugins deactivated I deleted the Forums menu and created a new menu called Test Menu. Again I selected secondary menu and double checked the Location. Indeed it is the secondary menu. I then just added one page to the menu (screenshots).
Of course I have deleted browser history and cache, and again I am stuck with secondary menu duplicating primary menu.
I really need a secondary menu for this site. Can you help please.
