Visits Page – Hover over Flag gives "xxx"

When I hover over a flag on the Visits page all I ever get is “xxx”.

I’m using newstatpress.1.0.9

The code for this is in includes/nsp_visits.php e.g. nsp_Spy()

foreach($lines as $line_num => $nation) {
    list($id,$title)=explode("|",$nation);
    if($id===$rk->nation) break;
}

$lines comes from def/domain.dat

Its format is lines like:
New Zealand|nz|

The order in the dat file is different to that expected by the code. I solved this problem for me by swapping $id and $title in the code:

list($title,$id)=explode("|",$nation);

Would you be able to incorporate this fix (or a swapped .dat file) in a later version please?
