Plugin: [google maps by wpmudev]

Hi,

I am having problems getting the map to log guests. The shortcode im using is:
[agm_show_checkins id=”8″ guest=”true” last_hour=”1″ is_responsive=”true”]

its showing guests from over 3 days ago and not 1 hour like the shortcode says. also its not logging new guests?

any ideas?
thanks.
