In shipping.class.php:
Find near lines 237-240:
$this->debug(sprintf('<strong>>>> Shipping zone [ID %s] matches the delivery address! Use this zone for shipping calculations.</strong>', $this->_all_zones[$i]['id']));
if ($this->_settings['multiple_zones'] == 'first') {
$this->debug('Looking for first matching zone of best match (instead of searching for all matching zones - see AIOS module settings)');
} else {
Change to:
$this->debug(sprintf('<strong>>>> Shipping zone [ID %s] matches the delivery address! Use this zone for shipping calculations.</strong>', $this->_all_zones[$i]['id']));
if ($this->_settings['multiple_zones'] == 'first') {
$this->debug('Looking for first matching zone of best match (instead of searching for all matching zones - see AIOS module settings)');
$closest_match_zone_id = $this->_all_zones[$i]['id'];
break;
} else {
The above is the exact same edit as was posted earlier, just the line numbers have changed.
