The WordPress at UNC Asheville multisite has been upgraded to WordPress version 5.6. The new version brings with it a new default theme and changes to the Page and Post editor.
See What’s New in Version 5.6
Upgrading to version 5.6 required an update to our WordPress server. Some of our system’s themes and plugins did not work properly on the upgraded server and have been deactivated. If you are currently using a theme that is not compatible with the new version of WordPress, your site will revert to the default theme.
Sites using a theme that has been deactivated (no longer available on the Appearance > Themes list), will continue to use the current theme. However, a site can not return to the “grandfathered” theme if another theme is activated.
