I recently discovered a strange thing.
for shipment method, the customer have the possibility to choice an option that does not exist in backend
If looking at the source code, i have:
<input type="radio" name="virtuemart_shipmentmethod_id" id="shipment_id_23" value="23" checked="checked">
I have no ID 23 in shipment option in backend
this only exist in japan version an english version of the multilinguage site
( English version: i discovered there are 3 differents mode already configurated with UPS.)
=> But, Where to remove this option given to customer ???
virtuemart 2.0.24c
joomla 2. 5.16
Finaly I used an other methode
=> directly erased the no-disered field of """ virtuemart_shipmentmethods_en_gb""" and """"virtuemart_shipmentmethods_ja _JP`""" with phpmyadmin
Nethertheless, i think there is a bug as you should do this directly using virtuemart interface !
Bye
