Fix for IE not being able to open vm admin
http://forum.virtuemart.net/index.php?topic=51089.0
can’t create or edit shipper in vm admin:
Search for:
$fields = array( 'shipping_carrier_name' => vmGet($d["shipping_carrier_name"]),
in administrator/components/com_virtuemart/classes/ps_shipping.php
and replace with:
$fields = array( 'shipping_carrier_name' => vmGet($d, 'shipping_carrier_name'),
Needs to be done in 2 places in this file.
Backup everything you plan on changing, because I’m not offering support is something goes wrong.
