Hi,

When ever we try to make a payment on our site it fails at step 5(order confirmation / confirm payment) stage and returns the following error within the page:
Code:
Error calling ProtX gateway. Msg=Request for the permission of type 'System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
We are using SagePay / Protx for our gateway.

This error occurs regardless of whether we use the live transaction server or otherwise.

The strange thing is I took over this site from another developer and moved to a new server. I had a complete backup of the old database and restored this on the new server. So the database should be identical, so why is this issue resulting??

Any help / advice will be greatly appreciated.

Thanks
