Geo Plugin problem but was working before

Hi all,

I’ve had the Geo plugin working with my WP install for a little while but something happened and I believe it could be to do with the $postdata variable and a recent upgrade to 1.5.1.1. One of the functions in the plugin goes like this:

function edit_form_advanced($not_used)
{
global $postdata;

$geolocations = get_settings('geo_locations');

echo '<fieldset><legend><a href="http://www.asymptomatic.net/_wiki/GeoPlugin">&#039; . __('Location', 'Geo') . '</a></legend>';

echo ("Postdata is: " . $postdata);

if(!in_array('post_lon', array_keys(get_object_vars($postdata))))
{
if(!Geo::prepare_database())
{
echo '</fieldset>';
return;
}
}

There’s more to that function but it’s crashing out on the !in_array line because $postdata doesn’t seem to be an array. In fact it seems to be blank. Anyone have any idea on whether the recent bug fixes would have messed it up?
