Hello,
I'm not able to add a custom or sample icon to a category or to a POI,
this is the dev.website:

http://w2.italyguides.it/en/campania/isle-of-capri/interactive-map-of-capri#!/catid=2

The only POI that works (I don't know how and why) also disappear at certain zoom levels or if you simply move the map.

When I try to save a category with a sample icon I got these error:

[21-Aug-2013 12:24:31 UTC] PHP Fatal error: Class 'JFile' not found in /******/administrator/components/com_hotspots/controllers/category.php on line 156

if (JFile::copy($sampleImagePath, $moveTo))


Any help?
