I have WP Super Cache installed. The Super Cache function works fine -- but the WP-Cache functionality for logged-in users/visitors does not work.
The plugin is generating WP-Cache files...I can look in the cache directory and see files like :

* 0 cached pages
* 0 expired pages
and pages when I'm logged in, etc. *always* say "Dynamic page served in blah seconds"
