cache
"If you are finding that your map loads slower than expected, you may need to configure read/write privileges on the _promaps_cache directory. This directory stores the XML file that is created when you first view your map. All map locations will then be read from the XML file to display faster in a browser."
What configuration will work? I have more than 300+ pins on a map and entire states are not showing up. I have deleted what seem to be problem addresses - e.g. commercial buildings with a suite number - but it still does not load everything. Any suggestion would be most welcome.
