submenu doesn’t show up and link color

Hello team, I used the elevatebiz pro theme for a website. Now I tried to convince others to use elevate biz. Therefore I use elvatebiz (not the elevatebiz pro). I have two problems. If I will use a submenu, the submenu is invisible. I see the submenu in the editor in the navigation part, but in the menu on the (home) page, the submenu items are invisible. The second problem is the link color. I tried to change the style on different positions, but the link color stays the same. Can someone Gove me a clue v=for a solution.   Kind regards   Hans Hagmeijer.
