Hey Chris,
Thank you for reaching out to us!
Based on the first error I see in your screenshot: “You have included the Google Maps API multiple times on this page.” , I believe that your theme or one of your active plugins is conflicting with Events Calendar PRO and calling the map scripts more than once.
To get started, I would recommend you to disable all other plugins and revert to a default theme such as Twenty Seventeen. If this eliminates the problem, try reactivating everything one at a time – testing at each stage to see if the problem comes back. That way you should be able to isolate any conflicts to one or more plugins (or your theme), which might get us on track to solving this. You will find more information about the Conflicts Test in the following article:
Testing Conflicts With Themes and Other Plugins
Let me know if you have any other questions in the meantime and I’ll be happy to assist!
Best Regards,
Patricia
