@johnpeterm you can go to your network settings page https://YOURNETWORK.URL/wp-admin/network/settings.php and uncheck the ‘Display the CTA banner’ setting to remove the banner:

If you want to edit the banner content, you can find the code for that in the pressbooks-book repo: pressbooks-book/header.php at c33128bf69dee37022691e887448dd62e8d171ef · pressbooks/pressbooks-book · GitHub

@SteelWagstaff Thank you.

I would like to replace with my own logo in the home page, appreciate if you could help me. See the attached image…
