I have established SobiPro entries with addresses under Categories.

On the map in my website however,

1. The map appears blue with nothing else on it.
2. The categories show up in search
3. City does not appear.
4. None of the SobiPro entries show up as listings on the map.

What could the problem be?

I have the exact same issue. This extension is useless at it is.

Map not loading, when viewing the quicklaunch, is there issues with this extention?
also can you load base maps and layers, like you can with other maps, like Leaflet.js?

I dont know how these people can sell an extension dont work ....
No support, no awnser, .... Good look, you'll need.
