The issue is on my LOCAL machine, you know – //localshost?? It is NOT on a hosted web server. I am running XAMPP on a PC and working on the website that way.
However, I can tell you that I did install your plugin to the site’s default host that IS on a hosted web server. The temporary setup is using the default WordPress 2013 theme, After installing your plugin on that server, I was able to add and save a map, and add and save a marker, That was on Saturday.
So, it could be that it’s an issue with XAMPP, or the //localhost on my pc, or the networked sites setup on my local WP installation, but it does work ok in a hosted environment with a single WP install.
