Refound

no site is still built, I just installed the theme, so I asked if it is possible to get a refund

You are right, but this time I have difficulty. In 5 years I have never asked for a refund because I’ve always solved the problems by myself, in fact I asked here how I can do it. I have already chosen a new theme.
If I can not have a refund does not matter, but before losing $ 50 I try.

Oh…
I just didn’t take it and I understand @c4web. This is the worst practice to break WordPress fundamentals like menus. Custom menu walker + a little of math are the way to go here. I’m sure that the author must fix such mistakes.

they wrote this morning, after I asked for a refund, saying they would fix it. Now I have asked how long it will take, but I’m afraid a lot and this is not okay either.
If you also bought this theme and you need the menu, write to them. If we are so many, they can make it fast

It’s not a navigation menu, it’s a restaurant menu (food items), essentially the post meta requires a bit of HTML input by the looks of things.
