View network blank page / Host by... empty host array

[kellerkind]

I have symlinked http://localhost/lanmap2/ -> /usr/src/lanmap2/web.
The db has a size of 130k after running capture so I can assume that there's already some data collected.

Before i performed all the steps from the README including creating the graph.

    Generating graph, may take a bit...
    done.

The site view by network is empty.
The host by shows this:

Array
(
    [hp_id] => 
    [id] => 
)

Hostname (ID=)
