After I successfully activated this plugin, then changed some of its settings, I experienced a blank white screen. I deleted the plugin and its database fields, reinstalled the plugin. After activation, I experienced the same thing. It seems to be expelling this string
xapi_geofence_callback? after my website url followed by by lat and long coordinates. Is there something else I need to delete in order to make this plugin work again? I've already tried turning off Geolocation in my browser.
