Hi,
since the hack, we updated page builder and the helix ultimate template.
But we can't set up the mega menus anymore. The hack added malicious code to a badge in one of our mega menu items that we removed. The main item exists now still but the subitems are all gone.
I access it by going to System -> Site Template Stiles -> shaper_helixultimate -> Template Options
But every time I try to add items to the row it doesn't work. It currently shows empty items in the row blocks and saving the page in the admin does not change anything either.
I also tried creating a new mega menu item and it shows up in the frontend but not in the mega menu list
