Upgrade Breaks Theme

I’ve recently upgrade my ghost instance to 4.32.0. Once I’ve upgraded my instance the theme I used to use, Massively seems to have broken.

I tried to get a few other themes from: Download Professional Ghost Themes - Envato Elements and it seems a lot of them are no longer compatible. Was there a major change I missed?

For now, if anyone is using Massively I’d love any insight on how to fix the Menu items.

Current upgraded version can be seen here Notice the menu items if you hover your mouse are barely visible.

The expected behavior is this

I think this can be fixed via a CSS inject, I managed to get the menu to no longer be vertical with this CSS I added, but it still doesnt look right.

ul.nav {
  display: flex;
  justify-content: space-between;
  list-style: none;
  margin: 0 5rem 5rem 5rem;

ul.nav li {
  background-color: white;
  padding: 3px 10px;
  border-radius: 5px;

ul.nav li a {
  text-decoration: none;

Any help would be greatly appreciated!
