Mellissa’s grid and list layout previews return 404
From the Live Preview in the marketplace. Click ‘Home’ > ‘Grid layout’ and ‘Home’ > ‘Flat layout’.
Edit: On another note: The tables are not responsive and do not work well on mobile (unless it’s just two columns and very content in each). Any plans of rectifying that? Buyers of the theme can implement that themselves, of course, but would be nice to have included.
