Hi Jeff!
Thanks for getting in touch with us!
Let me help you with this issue.
Could you please see if there are any console errors by inspecting the page? We have an article that explains how to do that here > https://theeventscalendar.com/knowledgebase/using-google-chrome-developer-tools/
Did you happen to notice a difference when deactivating all other plugins or switching to a default WordPress theme, like Twenty Seventeen? What happens if you try deactivating all plugins and switching to the Twenty Seventeen theme together? Do you notice a difference then?
If you see no difference in those conditions, then we’ll need to do some deeper troubleshooting
Let me know about it.
Thanks,
Victor
