Unable to submit iOS app for review - “There are one or more errors on the page.”

Question

I wanted to submit my app for the App Store on iTunes Connect, but whatever I do I got this last message telling me there are still one or more errors on the page.

Answer 1

My case was different when trying to submit a Newsstand app with an in-app purchase. Under the versions tab, I had to go to the in-app purchases section (NOT the in-app purchases tab) and add the free subscription I had configured to my build submission.
