The Google Map field in ACF is an interactive map field featuring a search input, location finder and a draggable marker. Sometimes you may be presented with a nasty error message instead of a map. Here is how you fix it.
The error message above is displayed instead of the map field when a Google API key is missing. To fix this you first need to get a Google API key, then add it to ACF using one of the methods below.
