[Plugin: WP Geo] Geo Mashup Map won't display all of my posts

Hello
I have 74 of my posts who are geotagged with Wp-Geo. Yet no matter how I try, I can’t get to display all of my posts on one single map.
I have tried using the wpgeo mashup shortcode, the wp geo template tags and the WP Geo – Mashup Map plugin but nothing will work. The best I could do achieve is, through the use of a wpgeo template tag, to display on one map all the markers of posts belonging to one specific category. But I would like to do this for all of my categories.

My website is http://www.monparispascher.com

Thank you
