Dima, I literally rebuilt the map as new, almost no options changed, added the placemarks back to it and all is working. Only thing I did change, was remove the apostrophe as well, I wonder if that was causing an issue?
One thing I did play around with, is trying to have the list panel with all the placemarks in this category on the side of the map, but I could not figure out the settings? The category ID is 106, that has all the waterfalls in it. Map id is 30. If I want to use the plugin and embed straight into the article, with the map id of 30, with the placemark list on the right, showing the placemarks assigned to that map in the category of 106, what is the markup for that please?
