I wanted to test out Max Mega Menu for building more complex Mega Menus. I am using the free version and when I activate the “Mega menu settings” on my primary Menu I lose all my Typography and color settings on that menu and it’s back to its default state.
I believe that plugin replaces our default navigation with their own, which explains why our colors/typography wouldn’t apply. It doesn’t look like it’s activated on your site right now, so it’s hard to tell.
