I have created a page containing a map with markers for all posts – of which there are about 30 posts – using Boris’s code.
[gmap marker_query="numberposts=-1" width="100%" height="400px" type="hybrid" center="markers,photos,files"]
However when I you load the page you can only see 3 or 4 markers. Does anyone know why this is. I am expecting to see posts appearing in Australia!?!?
