Reply To: Sticky menu stays transparent after i used call to action menu item

ok, sorry. I found it.
The problem was:
when i selected a color at > theme options > header > appearance > header background
Then
the sticky menu stays transparant on the home page.

Why do i select a color here?
Because the header looks fine on every page. Accept for product pages.
because the product page header is completely transparent, you can’t read the white menu texts.

So what i need is, a header/menu on the product page with a black background.
