I just updated to the latest version of The Events Calendar Pro and I have this message at the top of the WordPress Dashboard. The site is http://www.lowermaclib.org
The page “Events” uses the “/events” slug: the Events Calendar plugin will show its calendar in place of the page.
Edit the page slug or edit The Events Calendar settings.
Not sure what it means or what I’m supposed to change. The calendar seems to be operating as expected on the front end of the site.
