Java script error

#1
When I go to Campsites and view a campsite the map loads for a short time then changes to an error message that Google maps didn't load properly, see java script. Knowing very little of Android anyone point me it the easy right direction.

I've had the same issue, not only on my android phone, but also on my laptop. Chrome, Firefox and MS Edge all display the map for a second or two then display the error.
