I’ve added an “About Us” page to the site, and that seems to have taken care of the error message. Thanks for your help.
Is this something that I can only do if I pay for the theme, or is there code that I can put into the title header to make room for an ad?
There is no “Static Front Page” in the General panel or in any part of the Customizer.
It is a new site, and there are pages published – ntxtalk.com.
OK, how can I edit the theme file to add a banner?
I have deactivated all my plug-ins, and I’m still getting the error message.
