Hello Antonio,
Sorry for the trouble here! Let’s see if we can figure this out together.
There are a couple of things we can check to get started.
1) Venue Data. Often, the location search will fail if cannot fully understand the address or location information of an event’s venue. If you head to Events > Settings and scroll down to the “Map Settings” section, there is a button to “Fix venues data.” Click that and see if that helps make a difference.
2) Geolocation Coordinates. If #1 doesn’t do the trick, then try editing your venues and specifying the exact latitude and longitude coordinates for the location (screenshot).
3) Javascript errors. I see there are a number of javascript errors on the page, including one that the Google Maps API has been included multiple times. It’s possible that the theme is injecting the API in addition to The Events Calendar in which case, errors like this are totally possible. I would suggest clearing out all of those errors, and that one in particular.
Let’s start here and see what we find.
Cheers,
Geoff
