Primary Menu Bugg

Hello!

I’ve tried googling every possible combination for a fix.
Have also learned that im supposed to have a child theme.
Excuse me for not having that.

My primary menu have active elements in it.
Even when i have turned everything off.

They primary menu is also invisible.

Does anyone have any good bets of what could have happened?
I was using Max Mega Menu addond- i think it’s connected to that.

Would mean the world to me if this was able to solve
