I use CustomPress and have a range of custom taxonomies, and do not use regular Wordpress tags.
I want to create maps that either show all locations or those related to a certain custom taxonomy.
The usage advice for the plugin shows me that for a tag I would use [map query=”tag=my_tag"]. Ok, but I have tried this by inserting a custom taxonomy where my_tag would go - and nothing. Even [map query=”all”] shows nothing at all - as all of my 'tags' are custom taxonomies.
The maps per custom post work just fine (ie [map id="1"]).
