I wasn’t able to fix it, but I modified it. On the posts page, I used this code that I found online:
.main-navigation ul ul.sub-menu li a:hover, .main-navigation ul ul.sub-menu li:hover a, .main-navigation ul ul.sub-menu li.current-menu-item a, .main-navigation ul ul.sub-menu li.current_page_item a {
color: white;
background-color:#FFFFFF;
}
.sub-menu a {
background-color:#000000;
}
The colors aren’t the best, but it’s at least readable now. I can view the submenu and links on the submenus on all pages. I can’t get the submenu border color to be white on pages and keep it black on posts.
Any idea how I can do that?
