I tried both versions and end up with a blank map so I’m doing something wrong.
My shortcode is here…
[mashup show="query" width="100%" show_query="posts_per_page=25&category_name=members" directions="none" marker_body="marker"]
Another issue I am having is when you click on a marker. It’s showing a lot of text from inside the post for some reason, even though it’s set to marker_body “marker”. Admittedly, I am using your latest 3.83(?) beta so there may be a bug there.
