I’ve been using the Map widget in the same way for a couple of years and it’s worked well, until today.
I have two Google Maps with markers in various locations. For each marker, I include the name of the location in the Info Window. When I view the page, the markers appear in the correct locations, but, starting today, the info windows all appear with exactly the same text. They seem to be drawing from whatever is the last marker listed in the widget.
This is the page: https://www.sonomavalleyescapes.com/location
I deactivated all of the plugins, except SiteOrigin, but that did not resolve the problem. I created a new page with a new map, and the problem persisted. I updated the WordPress theme, but that did not help either.
