Hi,
The dimensions are using to calculate the "girth", in order to check that the package is not too big for shipping.
If you do not want to specify dimension, you can see to update manually the plugin, by replacing
case 'volume':
if(($product['x'] * $product['y'] * $product['z']) > $limit_value)
return false;
return (int)floor($limit_value / ($product['x'] * $product['y'] * $product['z']));
break;
case 'girth':
if(($product['x'] + $product['y']) * 2 > $limit_value)
return false;
return (int)floor($limit_value / (($product['x'] + $product['y']) * 2 ));
break;
By
case 'volume':
$divide = (float)($product['x'] * $product['y'] * $product['z']);
if(empty($divide) || $divide > $limit_value)
return false;
return (int)floor($limit_value / $divide);
break;
case 'girth':
$divide = (float)(($product['x'] + $product['y']) * 2);
if(empty($divide) || $divide > $limit_value)
return false;
return (int)floor($limit_value / $divide);
break;
