Problem resolved; I had collision with smint js script.
Comprehensive Google Map is great plugin by the way, Thanks for publishing!
I’v had same error with my feed, so I deactivated plugins, one by one, and realized that problem was in ‘Custom Field Images’ plugin. Bug is now fixed in 2.2.3 relese, so all you have to do is upgrade that plugin to latest version, if your error is related to this plugin.
