Hey Jennifer 🙂
I hope your New Year is off to a great start! I notice you’re running version 4.3.1.1 of PRO. Can you update to the latest version, then review the Testing for conflicts guide to see if the issue persists?
If so, it might be best you set up a fresh WordPress installation where you can fully troubleshoot the issue. Make sure you have only the default WordPress theme and The Events Calendar installed and activated on the test site. Please review our Using One License for Live and Dev Sites for more information.
Please make sure WP_DEBUG and WP_DEBUG_LOG are enabled on your site’s wp-config.php file. Any errors will display at the top of your page as you try to reproduce the conflict. Note what you find and please include it in your reply. Lastly, make sure the Create recurring events in advance setting is set to greater than 1 or 2 months prior to creating a recurring event.
Thank you and please keep me updated with what you find out. Cheers 🙂
