Thanks, i think i see the problem.
In geodirectory-templates/listing-listview.php please make the following 2 changes.
line 72:
To:
$uom = __(get_option('geodir_search_dist_1'),GEODIRECTORY_TEXTDOMAIN);
line 78:
To:
$uom = __(get_option('geodir_search_dist_2'),GEODIRECTORY_TEXTDOMAIN);
Please let us know if this resolves the problem.
Thanks,
Stiofan
