Shipment Method Information is writable - Configuration not writable

[liv]

Shipment Method  and Payment Method
Information is writable - Configuration not writable

I can add/change Shipment Method, but when I try to change the fields in Shipment configuration it will not be saved. I have checket the write-permissions for the files.
For excample if I try to set "gram" instead of "kilogram" it just goes back to "kilogram" when I save.

The same thing for Payment Method:
Information is writable - Configuration not writable

I have Joomla 2.51 and Virtuemart 2.03 but I had the same problem with Virtuemart 2.02

Usual reason for not saving is that you are not logged in as vendor.

But you said elswhere:

I have joomla 1.5.26 and virtuemart  2.0.20b. I have a problem with  shipment configuration: when I insert data as cap, weigth,cost... nothing is saving and  no one shipment method appear in the site. Can we help me? I have also reinstalled the plugin and aio but nothing change.
I can't use another version of joomla!!
Sorry for my english!!

Maybe this is one of those issues that appears when using Joomla 1.5 with VirtueMart 2 - It was announced that Joomla 1.5 is no longer supported for VirtueMart -   http://virtuemart.net/news/list-all-news/426-end-of-life-for-virtuemart-11-heidelpay-now-in-virtuemart-2012
