esmith, I suspect this is a coincidence as the timing of the OP’s problems coincides perfectly with my caching system installation.
Folks who are having a problem do me a favor and try this:
First, actually log out and then log back in again (You were never logged out in the first place, but were just erroneously shown the cached version of the page that is usually shown to logged out users.)
If it keeps happening, please let me know if you have a cookie called DRUPAL_UID set for piggington.com. If you have this cookie, you shouldn’t have a problem. I am hoping that the problem is that you didn’t have the cookie before, but that the logging out/back in will set it for you.
Email rich at piggington if you need more info.

UPDATE – PS – you have to allow cookies from piggington.com or you will continue having this problem.
