I am newly trying to fix a website that is built using WordPress and hosted by a third provider. The site has not been maintained as best I can tell for about 5 years. My main action so far has been to upgrade to WP 5.0.3.
But when I try to edit any page in the site (having gone in through WP's back end), I get this message on an otherwise blank page: “Please select a CiviCRM front-end page type.”
What does this mean and how do I fix it?
