WP SUPER CACHE ***DANGER****
Deactivating it does not stop it from reading old super cache files!
"If you’re logged in or have left a comment you’ll never see a super-cached page."
"You’ll see plain old regular WP-Cached pages instead."
That means if you log out and see something different, it's super cache screwing things up.
Do not install until you have been running a while.
Do not install unless speed is an issue.
Don’t forget to delete the files wp-content/advanced-caching.php and wp-content/wp-cache-config.php.
Also comment out the WP_CACHE and WPCACHEHOME defines in wp-config.php.
It says "Added by WP-Cache Manager" but that's super cache crap.
