The shot is not for the messenger. Don’t like when people criticize and don’t help even a little bit or provide an alternative solution.
From what I understand the problem is that you add items to the menu in the menus admin area and they disappear from there. Or they are saved and you can’t see them in the front-end?
if the problem is that your new items aren’t save you can test with Twenty 15 without checking being necessary to check it in the front.
Can you also provide admin access in a private reply?
Thanks
