Header Issue with Hide on Desktop, Tablet, Mobile – مرجع علم و فناوری

Blocks in the header that are designated to be hidden on desktop, mobile, or tablet are still showing on the 404, Search Results and other default theme pages. They are properly hidden on all other pages.

Here is an example of both the mobile and desktop headers showing on the 404 page: https://www.sensiblediversity.com/xyz/

I’m using the WordPress Twenty Twenty-Three theme with the latest versions of WordPress and Spectra. This issue is consistent across multiple sites.

Thank you.
