Website Header not showing full options

Site URL: https://www.workatwanderloft.com/

The website header had disappeared for weeks, at first I thought it was a glitch and the problem has stayed for weeks.

The original setting was "fixed position -> scroll back", if I chose to disable the "fixed position", the header reappears, but it's not showing the full options of the navigation list.

What should I do now?

Thanks!

Do you have any custom CSS or plug-ins related to the header. SS made changes to the header recently which may have manifest an issue with custom code.

I saw other similar posts about custom CSS or plug-ins, but I never made those changes recently.

Would there be a way to change back to default if I ever mistakenly changed sth on the CSS?

Upon further examination it does appear you've made some changes to the header with Custom CSS.

When SS makes changes custom code can break. I suspect that is what has happened to you.

To correct the issue you basically need to remove, make copy somewhere, the custom header code. Then rebuild the effect(s) from the ground up.
