@JohnHClark3 how are you making changes to
navigation.hbs and what environment are running in (development/production)?
If you’re editing the file on the server directly whilst in production mode you’ll need to restart Ghost after each change. However, if you’re uploading a theme via the admin panel then the changes should be immediate.
If you are using the admin panel, or restarting after making changes, and you still see a delay in changes appearing then we’d need more information to be able to help you such as your nginx config and details of any CDN/cache you have in front of your site.
