My site has a new problem with the header. The header has always been configured as follows:
- The logo appears at the top when you’re at the very top of every page.
- The menu navigation is in a separate bar below it.
- As you scroll down, the logo bar disappears and the menu navigation remains.
Recently, this started “jumping”. As you’ll see in this video, a black area briefly flashes half way down the page as the logo bar is disappearing:
How to fix?
I’ll provide login details in a secure note.
