(Mojave 10.4.2) Missing top right items (clock, network, battery etc.) I don't know what happened. I restarted mac and since then I don't have top right icons: network, sound, battery, clock, notification but from time to time it blink and for a moment become visible but immediately disappear.
I tried (and with sudo):

killall -KILL SystemUIServer
No matching processes belonging to you were found


I restarted mac and still same.
Is there any way that I can reset this icons settings?
And I repeat wired thing is that it blink as I move cursor and from time to time for a moment I see items.
And also skype, dropbox and spotlight icons are always there.
The following approach is suggested:


Navigate to the Library folder in Finder



  
  Open Finder
  Use Go -> Go to Folder  (Shortcut: Cmd+Shift+G)
  Type ~/Library and hit Go
  





From the Library, navigate to the Preferences folder.


Locate and remove the file named com.apple.systemuiserver.plist






Navigate to the folder ByHost which is inside the Preferences folder.


Locate and remove the file(s) named com.apple.systemuiserver.[random_number].plist

Restart your computer.


SystemUIServers handles .menu software amongst other things, and thus this is expected to resolve your issue.
