Top menu in PW disappear when editing page

[cehlo]

Hi folks,

do you have some ideas to my problem? I can´t really find the solution. When I am editing any page with different role than admin the top processwire menu disappears. Only happens while editing. See photo. 

Thank you very much for any help. 

Cheers.

I would try switching to a different admin theme and see if it still happens. It seems like the theme has been modified, so hard to tell what the issue is. Also, this could be related to permissions.
