Hello Amber,
1. Go to Permalinks in Settings and there you can change the slugs
2. The page is moved to this: https://vinethemes.com/documentation/foodicious-theme-documentation/
3. Please share your website url with us so that we can check the issue.
4. That feature is called Featured Boxes only. You can set the Featured boxes from the Appearance -> Customizer
5. Please check that you’ve enabled the Featured boxes checkbox.
If you’re still having troubles with the theme, then please let us know.
Thanks
