I've not touched the SSO script I have running on a test setup and was working just days ago but now it appears not to be.
When I log in to my test site, as a registered customer - I am redirected to the cart after authentication, as usual. When in the cart, I'm now presented with a box with `Welcome back! Enter your password to continue.` and it has two inputs for username/password. Why would this be appearing after being authenticated?
Like I said, I've not touched a thing in FoxyCart or the SSO script so is this related to an update or has the SSO authentication changed in anyway that I need to update my script?
