I have a problem displaying spatial extent in Geonetwork when I open some metadata record (as you can see from the image example). I get the right extent I previously defined in metadata editor, but when I come to the metadata view page, basemap doesn't show up.
There was similar problem explained here in gis.stackexchange, but that doesn't work for my case.
I am using Geonetwork 3.04, just installed it on Windows XP. It is not connected to any database nor server, cause I'm not very familiar with computing and everything (I just needed Geonetwork as a catalog for spatial data).
