Hello Chris,
Thanks for your help, my site is http://www.euroviajar.com, here is a destination post with a map: http://www.euroviajar.com/discoteca-egg-de-londres/ – this post has been updated and nothing happen. Also I removed the icons code from the functions.php and the POI still displays the same instead of post info.
I want to use custom icons, post name, thumbnail and description in the POI.
