The problem is that the jQuery “live” command has been removed in jQuery versions 1.9x and up. It has been replaced with “on”. The “on” command can replace the “live” command directly”.
I did a search and replace to change the string “.live(” to “.on(” in the wp-content\plugins\comprehensive-google-map-plugin\assets\js\cgmp.framework.js file, then saved that file as cgmp.framework.min.js in the same directory.
It worked like a charm.
