I’ve noticed a bug in the wp-gpx-maps_admin_settings.php file, where the Show Speed setting is saved but this is not reflected in the state of the checkbox on the admin page. I’ve added
$showSpeed = get_option(‘wpgpxmaps_show_speed’);
to the section at the top and changed line 152 to refer to $showSpeed rather than $showW, and it’s fine now.
Just thought I’d let you know for the next update. Great plugin btw thanks.
