I did insert the menu widget.
That was the problem…I was the problem
Removing the menu widget the doubled menu desapeared
I have doubled menu on left side too. I wanted to have two menus on the left, so I inserted another with widget, but when I realized that the other is the same as the original, I removed it from the list on the menu editor, but on the page is doubled menu not removed.(my site is “inovatori.hr“).
Thanks for help if any !
Solved by deactivating the unique menu in the widgets panel, just now I do not have menu-title.
