Please notice 2 bugs on com_hotspots/layouts/hotspots/single-map.php
map_height and zoom doesn't exist anymore.
You need to change to map_height_single and map_startzoom_single
on line 43
HotspotsHelperUtils::createJSConfig(array('mapHeightSingle' => $params->get('map_height', 200), 'mapStartZoomSingle' => $params->get('zoom', 12)))
replace to :
HotspotsHelperUtils::createJSConfig(array('mapHeightSingle' => $params->get('map_height_single', 200), 'mapStartZoomSingle' => $params->get('map_startzoom_single', 12)))
Can you please include this in next release ?
Thanks
