## WordPress not displaying the_content()

Question

My web site is not displaying the content on individual pages, though it is displaying content of blog posts. Here is an example page:

http://williamwolff.org/courses/pmpsj-spring-2020/

I have been unable to find a solution to this problem for about a month.

I have not made any changes to the loop code (at least I think it is the loop code; the file name for the theme is loop-page.php), which I have pasted below. Prior to this error, it worked fine for the last 7 or so years. I can see all of the content in the Edit Page section of the dashboard, so I know the content is there. The error happens even when I have deactivated all plugins.

Thank you for any suggestions.

<h2 class="entry-title"><?php the_title(); ?></h2>
<?php } else { ?>
