Good morning again Gene,
Issues with displaying the map usually stem from either Google API key being needed: https://theeventscalendar.com/knowledgebase/setting-up-your-google-maps-api-key/
It can also happen when there is some type of Javascript based error on your site (usually coming from some type of conflict).
The next step would be to go through our testing for conflicts procedure (preferably in a staging/dev environment or local install of your WordPress website) and let us know what you find out.
Basically the goal here is to revert back to a bare WordPress installation to see if the problem persists. It also allows us to pinpoint what the cause of the issue is.
But, before you do that, there are 2 things I would advise:
- Make a backup of your database
- Consider activating a “Maintenance Page” plugin if you are doing this on your live site (to minimize impact on your visitors)
Best regards,
Geoff B.
