[itgenetics]

Hi there - recently took over from another developer who set up this site. Client is using Secure Trading. The error message from the merchant is:

They're telling me all they're expecting is a 200 response. They think there is a redirect going on. I have checked all of the usual suspects. Have come up with nothing. Any help would be much appreciated.

Are you using any Phoca products? I found that was the issue.
