Hey!
I just found the solution for the same, it’s small coding error.
In line number 353 & 356 replace the “in_ex_city” with word “in_ex_pincode“
from line 346 to 360 code should be changed to this :
if($cod_enabled && $cod_pincodes){
$cod_pincodes_arr = explode(',',$cod_pincodes);
if($customer_detail['s_city']){
$shipping_postcode = trim($customer_detail['s_postcode']);
}else{
$shipping_postcode = trim($customer_detail['shipping_postcode']);
}
if($shipping_postcode && $in_ex_pincode=='include' && !in_array($shipping_postcode,$cod_pincodes_arr)){
unset($gateways['cod']);
$cod_enabled=0;
}elseif($shipping_postcode && $in_ex_pincode=='exclude' && in_array($shipping_postcode,$cod_pincodes_arr)){
unset($gateways['cod']);
$cod_enabled=0;
}
}
Hope this will work for next update of this plugin.
