An emergency release of WordPress has been issued just a day after the latest update caused problems.
31 October 2020 | WordPress

WordPress has issued a new release just a day after WordPress 5.5.2 caused problems with fresh installs and sites with auto-update enabled were updated with alpha (unstable development) code. 

This is not a cause for concern for our clients with Care Plans as updates are managed in a controlled way as part of a maintenance schedule.

To update your WordPress visit Dashboard → Updates and click “Update Now.”
