The Mapper code renders a map of the selected community, area, region or of the entire world with pushpins on the map for each I-Group.
The data for the map is created by the I-Groups code using the XLM data downloaded from MKP Connect. This data is formatted into a hidden div. The address of this div is passed to the mapper.js code which then renders the map.
As the I-Group code gathers data for the map, it writes diagnostic information into the diagnostics log file, so check this log to see what is happening. You can use the Notifications Demo to display this information.
Google introduced the requirement for an API Key awhile ago, so the map will render but immediately be covered up with an error message if the API Key is missing or invalid.
