I’m updating this thread with additional information that I hope will help diagnose the problem.
I have switched between all of the themes that I have installed and have found one theme out of all of them that does not create the error.
The default theme will not show any of the problems listed in my original post. The other themes – which have links for the pages – do produce the error.
Additionally, I have re-uploaded the classic theme “just in case” and have found this to not fix the problem. The classic theme does produce the error as well.
