Good evening Henry and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the map not showing up as expected.
I would love to help you with this topic.
By the sound of it, it looks like there is some type of conflict at play.
This is usually because of:
- A conflict with another plugin
- A conflict with your WordPress theme
- A template customization for the Events Calendar that requires updating
A first quick test is to simply temporarily revert back to a default WordPress theme such as twenty-sixteen to see if the issue persists.
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)
Let me know how that goes.
Best regards,
Geoff B.
