Strange line before footer

Hello. Here is a screenshot:

How can I get rid of those two lines?

Hello there,

Does that line present on all pages or just specific ones? Is there any link you could provide here, so I can check it directly?

Hello there,

Try adding this CSS code to Appearance > Customize > Additional CSS from dashboard.

    #secondary .widget-area {
      border: none;
    }

Now the homepage looks fine, but the other pages have still one line before the footer.
