Hi, those were just examples of how to enter the center. You’ll need to use them in your mashup shortcode, e.g. [mashup center="-32,122".... ]
If you look at the release notes for 2.38.2 it mentions that marker_body isn’t supported any more. You’ll need to use marker_link=”false” instead, e.g. [mashup center="-32,122" marker_link="false"]
