Nope it doesn't work.
Also, I could see markers showing on the map so it seems to be working correctly.
The chat module is preventing zooming out on the map: bad user experience.
The map default coordinates is set in 0,0, you may want to fix that.
For your users not shwoing up on the map, I have few questions:
1 Do your users have address set?
2 Do you use the default address field or another custom one?
