I'm using your module in Joomla within an internal DEV environment to choose a CMS (and modules) for a new website. Unfortunately there is no way to make it accessible to the public so you can access it.
Running the console (F12) in IE11 causing the browser session to crash, so I can't see if there are an JS errors. The issue is to do with saving the settings in the module; they just disappear after I have saved the changes, the map re-centres on Toronto and all items inserted are removed - it basically resets itself.
I'm not a developer, so I'm not experienced enough to start modifying code. If you haven't seen it before then I guess it must be something else - I'll try a similar mapping module and see if that has the same problems.
