I'm getting this error after flushing caches (UN Women):

This on the donate page:

Problem is that civi changed that signature so supporting multiple versions of CiviCRM for payment processors is a problem - in this case 4.3 has been ditched in favour of later versions I would say.

Unless you are on a new 4.5 install?
