Hello, I have an issue with the header disappearing suddenly on desktop devices, whatever the browser is even in incognito mode, if I purge all the cache it appears again, but suddenly disappears!
Even I tried creating a new header, the problem is the same!
How can I fix this issue?
Please deactivate all the 3rd party plugins and activate only theme-required plugins on the site and then check the issue. I am sure your issue will be solved. Then Activate the 3rd party plugins one by one and check which plugin is creating the issue for you.
Otherwise, if the issue still exists then keep the 3rd party plugins deactivated and share the WP admin login details of your site so I will check and give you a possible solution.
