Recently, I begun working on a new wiki focused on a certain novel. Decided to edit top navigation bar. Went to admin dashboad>top navigation>MediaWiki:Wiki-navigation and changed text to:
** Main Character
*** Main Character/Techniques
However, after saving, nothing changed. My top bar remains empty with only "explore" and "main page" in it. Just to make sure I am doing things right, I checked various guides and noticed something interesting. First, editing interface looks very new, and second, when you edit content and click preview, it suppose to show how would the topbar look, right? But for me it just shows normal text...
