Hi
I can't see an api key in the map api field
Can you try creating an api key and adding it to the maps - I'm not 100% sure if this will fix the problem but you will need an api key going forward due to changes to how Google allow users to use their map api
Just to warn you - you may need to add some bank details when creating the api key - I just tried this myself and it is asking me to add them but I am based in the UK england
