There are some changes happening at Worldpay that affect the URL that they use to take payments - now they are no longer part of RBS. This seems to have been in the pipeline for a while, and Worldpay say that as the deadline to change it has passed, the old URL could stop working at any time (when RBS turn it off). The info is referred to on the WP merchant login page.
The URL in v2.10 is defined in includes/modules/payment/worldpay.php at around line 80
needs to be changed toCode:$this->form_action_url = 'https://secure.wp3.rbsworldpay.com/wcc/purchase';
Code:$this->form_action_url = 'https://secure.worldpay.com/wcc/purchase';
