Hi Charles,
Man, sorry for the errors here! I’m happy to dig into them with you to figure out what’s happening.
The biggest red flag I see is that the admin-ajax.php WordPress file seems to be blocked from your site. This is the error I see in the console:
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
http://judocalendar.com/blog/wp-admin/admin-ajax.php
Failed to load resource: the server
The calendar replies on that file to load the page via AJAX, so the fact that it is being blocked, is missing, or is not loading for any other reason is the likely culprit for the map view not loading.
I see you tried deactivating all other plugins–did you happen to notice a difference there? How about when you a default WordPress theme (like Twenty Fifteen)? There’s likely a conflict here and following these steps will help us found that, if it exists.
Let’s start there and see what we find. 🙂
Cheers!
Geoff
