If you look at http://whodidgoodtoday.com/ then look at http://whodidgoodtoday.com/good-places/ you will see that they both have a MapPress mashup. The first one (on the home page) uses the built-in widget and the second one (in a page) uses a shortcode. Both of them need to accomplish basically the same thing.
The widget on the home page only shows three posts, for some weird reason. It has “All posts” selected in the widget settings.
The shortcode on the page appears to show all the posts without any problems.
Hi, sorry my slow reply, I was working on a new release.
It looks like the widget is gone, but if you like, add the widget back and send a login and I’ll try to trace it. It would also be helpful if you don’t mind upgrading to the latest version 2.38.8 so I can work from the latest code.
