I've installed the Interactive Data Maps extension on my wiki, but even trying to load a basic map image is failing, and looking in the browser console I see:

Skipped unavailable module ext.datamaps.core load.php:7:616
Skipped unavailable module ext.datamaps.bootstrap load.php:7:616
Skipped unavailable module ext.datamaps.site load.php:7:616

All advice I've been given involves checking these files exist server side and reinstalling the extension if not. Is this something anyone can assist with?
