Hey Ellesor,
Thank you for reaching out to us!
I’m sorry to hear that you are having problems to display your recurring events, let me help you to solve this.
Could you please make sure that both The Events Calendar (TEC) and Events Calendar PRO (ECP) are up to date (latest versions are 4.6.1(TEC) and 4.4.18(ECP))?
After that, please access your Dashboard and head over to Settings -> Permalinks for a permalink flush (no need to change anything, just visit the permalinks page: WordPress will automatically flush your permalinks once you visit it).
Be sure to clear your site cache and browser cache after this change.
I hope this helps! If for some reason the issue persists after the plugin update and the permalink flush, please share your system info with us and we will be glad do further investigate your case!
Best Regards,
Patricia
