This is a bug. See the attached screenshot:
I see the URL issue and I click edit and change the url to https://**. Previously, it was http://** because that was an old login from 2014 and scribd .com probably used http back then. The whole site is now https.
After editing to https, I click save and I still see this Warning banner on top.
Expectation: Banner disappears because the (right now, inexisting?) form check upon saving should have found out that the problem was resolved.
