Thanks for checking it out, Anders. We’ve tried deactivating the plugins and reactivating one by one, but that didn’t resolve it. Same issue in either editor. We also tried rolling back to an earlier version of WP, with no luck. No, we’re not running a child theme. The issue is happening with every page created in this particular site.
The same user has a similar site from fall 21, https://danceensemblef21.sites.grinnell.edu, which uses the same version of Lovecraft (2.0.1), the same version of WP (5.8.3), and the same plugin set … and uses full width page template with no problem.
