For the Locations functionality to work, a Google API key will need to be provided.
This system uses the Google Maps API, and their policy has since changed and they now require which has forced us to configure individual API's for each account. Originally we shared our Google API account to all our websites, but now Google has implemented API call limits and ours every month reaches it's limit almost instantly because it's being shared. These are the types of errors you will get when it has exceeded.
