For some reason, WP Super Cache is caching when my client is logged in. I haven't had this problem with my log in, but a couple times now I have gone to the site and the admin bar is showing, and it says I'm logged in as my client. I am not actually logged in as her, however, as it is just a static, cached page.
When I clear the cache, the site goes back to normal. Why is WP Super Cache caching a logged-in state? How do I prevent this?
