Of course, the obvious has been done.
1. the checkbox for all of the custom post type are checked at the setting page
2. the map on the custom post itself works fine
3. the query is: [mashup height="200px" width="660px" show="query" show_query="posts_per_page=-1&post_type=projects"] and it’s on the home.php file with the do_shortcode(); function
4. mappress pro version 2.38 (i guess it’s the most updated)
